I have always thought that the film version of DESK SET improved greatly on the stage version....and in fact I think the stage version would be a community theatre staple if it had been the same story.
HOWEVER in the stage version....Tracy's character is not the male lead....and in fact Bunny does end up with Mike.
I think that this is one of Gig Young's best performances - along with TEACHER'S PET - and I wish he had been the third wheel with Doris and Rock in PILLOW TALK, LOVER COME BACK, and SEND ME NO FLOWERS....especially the first two.... Tony Randall was never a threat to Rock Hudson, but Gig would have made it a more difficult choice....
