Robert Pattinson documentary Robsessed is almost upon us - but is it anything we haven't already seen before?

Though it bills itself as 'the first exclusive R-Pattz documentary', the trailer (below) features a compilation of old pictures and video footage inter-cut with talking heads offering such insights as: “It's almost like you go to bed one night and no-one knows you.

"You wake up the next morning and the whole is screaming your name.”

It's been suggested the DVD – released in the US and UK on November 10 - is a cynical attempt by UK distributor Revolver to cash in on the mania surrounding the Twilight heartthrob in the run up to New Moon.

Whether you think it's exploitation or just giving Robsessed fans what they want, it's sure to fly off shelves as Rob devotees scrabble to get another R-Pattz fix.
