When news first broke of Todd Haynes’ I’m Not There – the new Bob Dylan biopic, in which different incarnations of the enigmatic Robert Zimmerman are played by six different actors, including Cate Blanchett – responses among Dylanophiles could have been described as mixed. While some saw Haynes’ casting as an artistic response to Dylan’s frequent acts of self-reinvention, others sensed just the kind of arrant gimmickry which might once have prompted cries of “Judas” (an anxiety not entirely allayed when Blanchett’s performance won her the best actress Golden Lion at the Venice Film Festival). Far from being the wilful travesty, Haynes’ film actually taps into a great tradition of “out-there” pop movies.

At number five in the rundown – narrowly beating off stiff competition from I’ve Got A Horse (1965), in which Billy Fury shares screen-time with his own racehorse comes Nicolas Roeg’s The Man Who Fell To Earth (1976). While this sublimely creepy story about an alien who comes to earth to find water for his own dying planet was not marketed as a biopic of its other-worldly star (David Bowie), it fulfils that brief beautifully.
