Shia LaBeouf's third and final turn as Sam Witwicky in Transformers 3

MANILA, Philippines - Transformers star Shia LaBeouf has revealed that the third instalment of the hugely popular franchise will be the most spectacular yet.

Directed by Michael Bay, Dark of the Moon will complete the trilogy with some “insane action,” all in state of the art 3D, says the star, who returns to play Sam Witwicky and is joined by a newcomer, Victoria’s Secrets model Rosie Huntington-Whitely, plus a stellar cast.

“The last 30 minutes of the movie is the craziest action sequence he has ever filmed in all of Michael Bay’s entire career and he would attest to that. It’s unbelievable,” says Shia.

“Think about it, if you are going to make a Transformers trilogy you know that the last 30 minutes of that trilogy you have to deliver the most insane action sequence that anybody has ever seen. It has to be that way and it is that way. It really is outrageous and incredible.”

Bay has pushed the 3D technology developed for James Cameron’s film Avatar even further, he says. “A film like this defines what summer fun is, it does what a summer blockbuster is meant to do which is essentially provide a fun movie experience.

“The third film is darker and it has the action that you have in the first two films but this time it’s even better. We basically took the cameras that were used in the Avatar 3D room and put them on the head of a skydiver so the cinematography is outrageous and Michael is pushing the limits in that way. “

Rosie makes her acting debut in Dark of the Moon, playing Sam’s new girlfriend, Carly, and her leading man paid tribute to her total commitment to the cause, saying that the beautiful supermodel definitely has a future as an actress.

“It was a baptism of fire for Rosie,” he says. “But Rosie is incredible. For a start, she’s a great person to be around and has fantastic energy, which is always nice because if you are going to spend six, seven months with someone, it’s great if it’s someone you enjoy spending time with.

“Rosie is very diplomatic and sociable, she’s cool and she knows how to deal with life and she is very comfortable and she knows how to deal with Mike. She owns her sexuality, which is very important for a woman in Mike’s movies. She doesn’t have any shame in being able to help the director explore her body in cinema — she doesn’t mind it because she comes from that world of modelling.”

Shia says that the Transformers team went into the third movie well prepared and they were all determined to make Dark of the Moon the best Transformers experience yet.

“On this one we had a firmer foundation at the outset and as crazy as the Transformer movies get — and we do have injuries here and there and some really tough ones to deal with — I think in the end the movie is the best movie we have made and also was the greatest journey in terms of my enjoyment of it actually on the set.”

He adds, “I had more fun on this movie just in general, just being around. I think Michael has also calmed down. My relationship with him has really changed and we have such a strong friendship now and it’s nice to have that with your director.”

Shia also gave a taste of what the fans can expect in terms of storyline.

“Sam has found a woman, Carly, who nurtures him and wants to build him up. And that’s where they are when you meet them. And the whole thing kicks off when the Decepticons start looking for this secret artefact that the Autobots have.”

Transformers: Dark of the Moon will have strong characters — Patrick Dempsey, John Malkovich and Frances McDormand have joined the cast — a gripping story and those hi-octane action sequences that Bay is famous for.

Transformers 3: Dark of the Moon is released and distributed by United International Pictures through Solar Entertainment Corp.
