Arnold Schwarzenegger doesn't think 'Terminator Genisys' needs James Cameron's help.

The 67-year-old actor has insisted the fifth film in the 'Terminator' franchise is good enough to stand on its own and is annoyed that Paramount is showing a promotional video, where the original films' director is endorsing it, as he had no involvement in the latest offering.

Speaking to Collider, Arnold said: ''I do not like the idea that the studio went out and used it as a promotional material for the movie because I always felt that if you do that, it looks kind of like you need James Cameron to say something good about the movie.

''Which we don't, because the movie is a straight 10, it's a fantastic movie.''

The 'Predator' star's comments come after Paramount premiered a promotional video earlier this month in which the 'Avatar' director told fans, ''You're gonna love this movie'', and said he considers it the true third film in the series.

While Arnold is very proud of 'Terminator Genisys', he recently admitted that he found shooting the nude scenes ''embarassing''.

He previously said: ''[Nude scenes] are embarrassing, but fun. It leads to funny conversations and funny dialogue and great humour and everything like that.

''It's inevitable, you have to do it because it's what the movie shows, and there are certain times you can cover things up, and there are certain times you don't and you can't. So what? I don't think there's anyone here that has anything to hide.''
