Main cast members directing episodes isn't that uncommon. ... that's just from a tiny sample from shows I've watch/ed.
 * Criminal Minds: Matthew Gray Gubler - 9, Thomas Gibson - 6, Joe Mantegna - 4 episodes
 * Bones: David Boreanaz - 10, Emily Deschanel - 1 episode
 * White Collar: Tim DeKay - 3, Willie Garson - 1 episode
 * Elementary: Lucy Liu - 3 episodes

Less common is one of the main cast members to write an episode for an established show, e.g. Kirsten Vangsness wrote two episodes on Criminal Minds. Then you can give your character all the cool lines.

More awkward is for actor to direct his own character's love scene.
