<p>It’s far too old, but my vote for the best cast ever goes to “Sleuth” – with basically two characters, Sir Laurence Olivier and Michael Caine. (Yes, a couple-few supporting actors, but basically just the two of them for two hours.)</p>
<p>(And I’ll give a supporting nod to “Hannah and Her Sisters”.)</p>
I think that line is from Annie Hall (another personal fave, although definitely older than 15 years )</p>
<p>Moving on to the silly, but still IMO a great cast: Rat Race. Jon Lovitz, Whoopie Goldberg, John Cleese, Cuba Gooding Jr., Seth Green, Mr Bean–I forget his name.</p>
