Sean Connery's is good. Through his campaigning in the 60's to get fair pay for actor's he is the reason actor's get paid so much in present day. He is one miserable, dour porridge gobbler though.
I may be wrong but Howard Matks always struck me as a bit of a fantasist. On the few occasions I have spoken with him he got on my tits to be frank. The book is a good read but I took it all with a barrow of salt.
I heartily recommend any of Henry Rollins' travel/tour diaries. Get In The Van is...
I found Peter Kay's autobiog very good. I used to have strong connections to Bolton and recognised a lot of the places he writes of but a damn funny read for anyone.
Michael Caine's one is good, if a little self congratulatory but very interesting.
Stephen Fry's autobiographies are tip top.
