Answer:
Phil Collins starred in the following films/tv programmes:
The Beatles' 'A Hard Day's Night': as a young boy, but his scene may have been cut from the final version of the film
Calamity The Cow: A series. He was a teenager then
Miami Vice: A series. He starred in a couple of episodes in 1985
Buster: The main role in the 1988 film regarding the true story of Buster Edwards, one of the men involved in the 1963 great Royal Mail rain robbery (if you have not yet seen it, watch it...it is immense!!!)
Frauds: 1993 film where he stars as Roland Copping, a rather odd character if I may say so myself...(also watch that too!)
Hook: he had a very small part in that film (you know, the one with Robin Williams and Dustin Hoffman)
I think that's all of them, do forgive me if I'm wrong...I'm supposed to be doing my homework!
