The 10 worst pop stars turned film stars – in pictures

1 Jessica Simpson Once, people said that Jessica Simpson could become a viable acting proposition. Then people saw Jessica Simpson act . And now nobody says that any more.

He actually played himself, but with all the panache of a regional Michael Jackson lookalike competition bronze medal winner. Let us call this the Spice World effect.

He can also act like nobody else on earth . Because everyone else on earth is better at it than him.

Unlike Eminem, he then made lots of direct-to-DVD filler that people only watch out of self-loathing.

Her place here is well deserved.

And that was her being nice.

Your mum, given the chance, could grunt at a Transformer more convincingly.

Roger Daltrey did both. Greedy. Pictured: Buddy's Song (1991) Photograph: Rex Features/Moviestore Collection / Rex Feat 10 Geri Halliwell One scene in an episode of Sex and the City . A cameo in Crank: High Voltage. Fat Slags. That’s all of Geri Halliwell’s acting career. Oh, and she was in Spice World. I rest my case.
