There's no need to scream when it comes to Hayden Panettiere's new role in Shriek 4. She says, regardless of the rumours, she loves her new role on the fourth instalment of the popular horror franchise.

Despite reports of on-set problems, last-minute cast changes and issues with the script, Panettiere told Access Hollywood she's having a "really good time" on the set and that the crew is having a "blast."

The Heroes actress said: "I don't know whether it's somebody projecting or, who knows where it came from, but ultimately, it was untrue and I love my character. I'm having a really good time doing it. It's a really great cast."

She is in good hands, she insisted. "All the original cast is back. We have Neve Campbell and David Arquette and Courteney Cox. We have a brand-new cast: myself and Emma Roberts."

The praise didn't stop there, with Panettiere, 20, extending her adoration to the director.

"Wes Craven is amazing and such a nice guy. It is such a pleasure to work with him. You can feel the crew is at ease.

They're able to have fun; it's not like twisting their arm to come to work. They really enjoy it, so it's been a blast thus far," Panettiere said. She admitted she isn't in a rush to return to the small screen.

"I'm focusing mainly on film. I like to keep an open mind about everything involving this industry, and there's nothing specifically I want to do."

Heroes star Hayden Panettiere has revealed that she is having a 'blast' while filming Scream 4. The actress was spotted laughing with co-star Emma Roberts, 19, as the pair took a break from filming in Detroit. Talking about the movie, Panettiere told MTV News: 'For an audience that is so well-versed in Scream [films] and in what happens and who becomes the killer, it's trickier to throw them a curveball.'

She added: 'I think they've done a really cool job with the script, [and] we've had a blast on it.'Scream 4 is the fourth instalment in the slasher film series and is scheduled for release in April 2011.

If you’re looking for production problems, they’re not on the set of “Scream 4.”Since cameras rolled on Wes Craven’s horror sequel in Detroit, Michigan, the internet has been rife with gossip, i.e. Lake Bell dropping out before filming and “Heroes” actress Hayden Panettiere ticked off over the script.

The actress tells Access Hollywood, “I don’t know whether it’s somebody projecting or, who knows where it came from, but ultimately it was very untrue and I love my character… I’m having a really good time doing it. It’s a really great cast.

“Wes Craven is an amazing human being and such a nice guy. It is such a pleasure to work with him… you can feel the crews at ease. They’re able to have fun – it’s not like twisting their arm to come to work. They actually really, really enjoy it, so it’s been a blast thus far.”The fourth slasher installment stars its original cast members Neve Campbell, David Arquette, Courteney Cox as well as newcomers Emma Roberts and Panettiere.

With filming of the fourth chapter in the "Scream" franchise under way in Michigan, fans are hard-pressed to find out new details about the fourth film's notoriously mysterious plotline. However, when MTV News recently caught up with Hayden Panettiere, she said she's confident the filmmakers are doing the previous movies justice and that the process so far has been a blast.

"I think it's just perfect timing, the amount of time that has passed since the last one came out," the former "Heroes" star told MTV News. "It's a perfect setup, with all of these films ... the [fictional] 'Stab' [movies] and all the things like that. I think with all of the 'Scream' [films], the idea is to throw the audience for a loop every time."

Panettiere acknowledged that for savvy audiences, the surprise factor is an even bigger challenge this time around.

"For an audience that is so well-versed in 'Scream' [films] and in what happens and who becomes the killer, blah, blah, blah, it's trickier to throw them a curveball," she said. "I think they've done a really cool job with the script. We've had a blast on it."

Panettiere also heaped praise on her castmates and director Wes Craven. "Wes Craven is, he not only is the nicest human being, but he's a brilliant director. And it's all the original cast as well: Neve Campbell and Courteney Cox and David Arquette. We've got an incredible new cast that's come in, and we have a pretty good team." The spunky actress said she couldn't reveal too much about her character Kirby, only that she's "edgy, sassy and smart. She's a very strong character.

Scream 4 filmed several scenes at Woodworth Middle School, 4951 Ternes St Dearborn, MI which was converted into Woodsboro High School for the film. Though it was previously suspected the school would be used for a flashback scene, it was actually used for current high school shots starring Hayden Panettiere, Emma Roberts and Marielle Jaffe.

In the first scene, the girls filmed an exterior shot in which they started walking toward the school and another character runs up to them and interrupts their conversation. Later in the day, they filmed interior shots in a classroom, the scene also included 2 buses filled with extras and 3 TV vans. Though you’ll notice in one of photos below, Hayden was given a chair so she could down inbetween takes, she was anything but a diva while on set. We even heard that after one of the extras hit her head, Hayden went over the ask her if she was OK.

Hayden Panettiere looked the cat's whiskers as she paraded around on the beach in a Hello Kitty bikini. The 20-year-old happily flaunted her tanned and toned figure in the two-piece during a recent visit to Malibu beach. Perhaps the actress, who recently had her long blonde tresses cut into a stylish crop, has been taking fitness tips from her boxer boyfriend, Wladimir Klitschko.

She has been dating the 34-year-old Ukrainian since late last year. 'I've never had an athlete as a boyfriend before, and it's an exciting experience,’ she said recently. Heroes, the TV show which made Panettiere famous, was axed in March by the U.S. NBC network after a dramatic loss in viewers. But creator Tim Kring is keen to bring the drama back for a mini-series in order to wrap up loose ends. Meanwhile, the young actress has joined the cast of horror flick Scream 4, where she will star alongside Courteney Cox and Emma Roberts.

Save the whales, save the world? Former Heroes star Hayden Panettiere seems to think so. The 20 year-old's advocacy on behalf of the hunted whales of the world — particularly in Japan — surprised many who pegged her as merely a pretty young starlet. But in October 2007 she joined the fierce anti-whaling advocates of Sea Shepherd in their attempts to disrupt the annual whale hunt in the Japanese village of Taiji. The activists were quickly dispelled and kicked out of Japan, but the protest became part of the Oscar-winning documentary The Cove.

In 2008 she created the "Save the Whales, Again!" campaign and auctioned off dinner at a famous Hollywood restaurant and a date with her on a whale watching trip to raise money for the cause. It was briefly reported that there was a warrant for Panettiere's arrest in the village, but the Japanese government denied the claim. In March, she returned to Taiji to meet with local officials about their whaling practices. On June 23, during the annual meeting of the International Whaling Commission, heated talks over whether to limit whaling broke down without a resolution.

At just 5ft 2in, Hayden Panetierre isn’t exactly the tallest actress in Hollywood. But the diminutive star looked even smaller today when she was accompanied by her giant boyfriend boxer Wladimir Klitschko who stands at a massive 6ft 6in. The Heroes actress’s flat shoes didn’t exactly help her out as she and Klitschko grabbed lunch at Il Pastaio restaurant in Beverly Hills.

She has been dating the 34-year-old Ukrainian since late last year. 'I've never had an athlete as a boyfriend before, and it's an exciting experience,’ she said recently. The 20-year-old star looked happy, if a little small, in denim shorts and a loose tie-dyed peach top. She recently had her long blonde tresses cut into a stylish crop. Heroes, the TV show which made Panettiere famous, was axed in March by the U.S. NBC network after a dramatic loss in viewers. But creator Tim Kring is keen to bring the drama back for a mini-series in order to wrap up loose ends. Meanwhile, Panettiere has joined the cast of horror flick Scream 4, where she will star alongside Courteney Cox and Emma Roberts.

Hayden Panettiere still has the measure of her giant boyfriend. The Heroes actress may come up short against her boxer lover Wladimir Klitschko. But she led the way after they had lunch in LA and we bet she wears the trousers... after alterations.
