I think I'd like more of a sports commentary going on. Morgan Freeman for the calm average bits, Stephen Fry for the sleepy time/sad emotional bits, Alan Rickman for when I want some dry wit, Brian Blessed for the exciting bits, a woman with a slight French accent (think Leliana form DA:O) for the romantic bits, Patrick Stewart for the important parts, Leonard Nimoy for the bits when I'm thinking and either Russell Howard, Frankie Boyle, Andy Parsons, Dara O'Briain on a week by week rotation for the funny parts.
See it'd be great with all these people, sometimes describing what's happening and sometimes making commentary.
(I know most of them have been said but there is a certain group of people with epic voices).
