Danny Boyle says 'Slumdog Millionaire' and '127 Hours' are ''the same film''.

The 'Trainspotting' director admits his latest efforts, including his most recent production, 'Trance', all bear striking resemblances to each other because they feature similar themes about memory and a main character who always overcomes a seemingly impossible task.

He said: ''All the films I've made are the same film, I have to admit that.

''They're all about a character - usually a bloke - who faces insurmountable odds and overcomes them.

''If you think about it, 'Slumdog Millionaire', the guy in '127 Hours', they're the same film. Don't tell anyone!''

While memories feature heavily in 'Slumdog' and '127 Hours', Boyle insists 'Trance' takes on a slightly different approach in that the film portrays recollections wreaking ''havoc and destruction'' instead of being used in a positive light.

He added in an interview with Nuts magazine: ''The last three films I've done have all been about memories. In 'Slumdog Millionaire', memory was a good fortune to Dev Patel.

''In '127 Hours', where he cuts his arm off, memories save him. This is more about how memories can wreak havoc and destruction.''
