We'll have a gay old time.........

Here's an interesting thought. A good portion of men in ameteur theatre are gay. A good portion of the professional actors I know are gay. Then how come television and film manages to only cast straight men? A few have slipped through the cracks but the rest are avowedly hetrosexual. Makes you wonder if somewhere in Hollywood there isn't a closet big enough to fit the cast of Ben Hur.
