Hey, I heard a rumor that Richard Kline is Kevin Kline's brother. Doesn anybody know if it's true or not? Thanks!

I looked up both Kevin and Richard's Kline's biographies on the web, and I couldn't find any mention of the men being related. I can't say for certain, but I don't think they're brothers.

on the IMDb, it used to say under Kevin's bio that they were brothers, but it didn't say anything under Richard's. Now it's disappeared on Kevin's so I'm guessing that it was an error. Thanks though!
