Eagle-eyed TMZ told you how Isaiah Washington was seriously PO'ed when he saw a promo for "Gray's Anatomy" that featured his axed character – and now he's taking action.

Isaiah has filed a formal complaint with the Screen Actors Guild over the promo, alleging that they can use the character, but not the image, to advance a story. Washington's Dr. Preston Burke was featured in a news story that Sandra Oh gazes at in the offending clip.

Peter Nelson, Isaiah's lawyer, tells Reuters that they are looking for a "financial settlement."
