Jason Flemyng thinks Will Smith's 'I, Robot' is ''rubbish''.

The 'X-Men: First Class' star hasn't been able to finish the dystopian science-fiction flick because it is ''unwatchable'' and every time he puts it on, it sends him to sleep.

The 48-year-old British actor said: ''That Will Smith movie, 'I, Robot'. I just can't get through it. The first couple of times, I'd think, 'I'm just tired,' because it's right up my street. I love Will Smith and I love sci-fi movies. It was a big hit, and I'm like, 'It's just because I'm tired.'

''But no, it's not because I'm tired, it's rubbish. It's unwatchable. It sent me to sleep. Every single time I've tried to watch it I've fallen asleep, like I'm narcoleptic.''

By contrast, Jason said Angelina Jolie's 'Unbroken' is ''terrific''.

He told Total Film: ''I watched 'Unbroken', Angelina Jolie's movie. I mean, it didn't serve it very well being on [a plane], but it was terrific.

''It's just such an incredible story: how much can you throw at a guy' The thing just went, 'Please take your seats...' just as the war ended, so I hope to God he got home, I'm presuming he did.''
