Shia LeBeouf returns for the second movie in the series
A release date has been announced for the third movie in the Transformers series, three months before the sequel even hits cinema screens.
Paramount says the film will be ready for 1 July 2011.
However, director Michael Bay said on his official website that Paramount have made a "mistake", stating that its release date will be in 2012.
A first sequel, Transformers: Revenge of the Fallen, is set for a summer release on 24 June.
It is one of the summer's most anticipated blockbusters.
In a comment posted on Tuesday, Bay said: "I said I was taking off a year from Transformers.
"Paramount made a mistake in dating Transformers 3 - they asked me on the phone - I said yes to 4 July - but for 2012 - whoops! Not 2011!!!
"That would mean I would have to start prep in September. No way. My brain needs a break from fighting robots."
The first film was one of the highest earners of 2007, making $708.2m (£503.5m) worldwide.
Shia LeBeouf reprises his role of teenager Sam Witwicky, caught in the middle of a war between two races of transforming robots, the Autobots and the Decepticons.
The films are based on the hugely popular line of toys launched in 1984.
