Penny Marshall and Dennis Rodman
 

Lately, (Penny Marshall) has been working on a documentary about the basketball player Dennis Rodman, some of which she has been shooting via Skype. That came up because a) Ms. Marshall is a big sports fan. ("You can yell and scream at a game and no one's taking you away in a white coat.") And b) "I have a little radar to the insane," she said. "They seek me out. Dennis and his agent asked if I would do a documentary."
