'Training Day' Writer David Ayer Files For Divorce

David Ayer, the guy who wrote "Training Day," "S.W.A.T." and a bunch of other action thrillers and also directed "Suicide Squad" is about leaving his 14-year marriage.

David filed for divorce Wednesday in L.A., citing irreconcilable differences. He married Mireya on September 26, 2002 and lists the date of separation as July 29.

There's a sign this one is amicable. David's lawyer, disso queen Laura Wasser, checked the box
agreeing that her client would pay Mireya spousal support.

They have 4 minor children - 14, 12, 11 and 8. David is asking for joint custody.

David who also wrote "The Fast and the Furious" and "End of Watch" - will be writing a big check, because it's been said there was no prenup, and he has made cool millions in the entertainment world.
