Arnold Schwarzenegger has ruled out making a sequel to 'Junior'.

The comedy movie - which was critically panned - starred the 67-year-old actor as Dr Alex Hesse, a research geneticist who falls pregnant after taking an unapproved fertility drug, a role which Arnold has promised never to revive.

The former Governor of California said: ''There's certain movies that we went a little overboard.

''The fact of the matter is, this is life. You make movies and do things. Some of the stuff is successful, and some stuff go down the toilet.''

The father-of-five added that he was expecting the movie - which also starred Danny DeVito and Emma Thompson - to be much better than it actually was when it was released in 1994.

He said: ''I've had great successes and a lot of things that went in the toilet and failed. There's no science to the whole thing.

''You read scripts and think it's a great idea, and then when you see it and realise that it's not quite how you envisaged it, you move on.''

However, Schwarzenegger - who will reprise his Terminator character in 2015 in 'Terminator: Genisys' - confirmed there will be a 'Twins' sequel, entitled 'Triplets', and also revealed a sequel to futuristic action flick 'The Running Man' is in the pipeline.

During a Q&A in London on Friday evening (14.11.14), he explained: ''They're doing a 'Twins' sequel, to be called 'Triplets'. I've read the first draft. There's rumblings of a new 'Running Man' movie, so it's a great honour to be asked back.''
