There was nothing quick about the debate between Dylan Penn and father Sean Penn on the set of their latest film.

The father-daughter duo performed together on the Late Show on Thursday, August 19, where host Stephen Colbert asked if there was a disagreement while Sean directed his daughter to star in Flag Day, which debuts Friday, August 20th.

“We had a major … I think it was a two-hour standoff over a note he had,” Dylan, 30, answered frankly. She went on to explain that “it was a matter of whether or not I could wear mascara”.

After Dylan shared, “He won,” the host quipped. “This is an argument a father usually has with a daughter when she is 12.”

Stephen then asked, “Did you have this fight in a private location, or was it a knock-down, a kidnapping in front of the crew?” As a result, Dylan immediately replied, “No, it was very public.”
