Here’s the scene:
A gentleman is taking a girl with himself outside the bar, but a group of guys stand in front of him, ready to fight.
The gentleman his limo driver to show his gun from under his suit, and says “that is the magic”.
I thought that the gentleman was Richard Gere and it was Pretty Woman (1990). But I looked that movie again and couldn’t find this scene.
I recall a deleted scene like that from Pretty Woman (I have the director’s cut dvd). Don’t quite recall the “magic” line though. This video on youtube shows the deleted scenes, the one you might be thinking about starts at the 5 minute mark.
