 Apparently Ray Liotta (qv), as one of the "good guys" felt that he  should dislike the actor playing a "bad guy",  John Mahoney (I) (qv), both on and off the set; when he saw  Mahoney in wardrobe or makeup, he would either rush out of the room  or immediately end all attempts at conversation. At the end of the  shoot, Liotta smilingly approached Mahoney and told him it was a  pleasure to work with him, to which Mahoney replied, "I wish I could  say the same."
