I think you're saying Robert DeNiro diretced himself in "Heat". For all I know, that may be. Al Pacino's pouty little wife in that movie put in a great performance
DeNiro came off like a blank in that movie. So much so that going after the bad guy at the end seemed out of character. Pacino, the wife, and even the kid gave great performances. There's a speech he gives about the house and drug use, etc. that's a classic.
