Rob Pattinson Struggling to Explain Remember Me Plot

Actor Robert Pattinson is struggling to handle the promotional interviews for new movie Remember Me - because he was not given the same media training as he was for the Twilight series.

The British hunk confesses his every move during The Twilight Saga: New Moon promotional tour last year was carefully calculated and he was well rehearsed on the kinds of questions he would face.

But he's not had the chance to practise his answers for new drama Remember Me and has been left speechless on several occasions - because he can't even explain the story plotline with ease.

He says, "(With Twilight), I got so used to all the answers. I remember going on (U.S. TV's Late Show with David) Letterman for the New Moon junket and I was terrified.

"(But) I get asked the same questions all the time so I prepared all my answers just before and I was so comfortable as I walked in. Every little nuance, every little mannerism is all planned out. Now people ask me what the film's about and I'm like, I don't know!

"I've been having so many problems trying to explain what it's about. Essentially it's about, I suppose, two people falling in love with each other, but it's not the central story. Well, it's one of the central stories."
