I don’t think that’s it - I think I’d know it if someone suggested it. He’s definitely in outer space, on the bridge of a big ship with a crew - IIRC a crewmember asks him what they should do - the good guys just got away? (Not sure about that). And that’s his answer.
Galaxy Quest? When the good guys have first flown through the minefield, the chief bad guy replies “Patience, lieutenant…Patience” when one of his underlings asks if they should follow the good guys into the minefield.
The bad guy in question is “General Sarris”, a sort of insecto-reptiloid, if that rings any bells.
“The Last Starfighter” does sound like a possibility. Maybe the scene where Dan O’Herlihy (General Black from “Fail Safe”) in a reptilian alien garb is telling the kid pilot to wait until all the enemy ships are within the proper range to activate the “Death Blossom”?
Man, you’re totally reading my mind. This is exactly what I thought of when I read the OP. Maybe it always comes to mind first because I have a friend who responds that way every time he’s asked “So, what do we do now?”
