Actor Paul Rudd found himself in trouble with police in Atlanta, Georgia earlier this year (13) after accidentally brandishing a prop gun while trying to break up a fight.
The Knocked Up star was filming Anchorman 2: The Legend Continues when an altercation broke out near the set.
Rudd rushed over to help keep the peace, but cops soon turned on him after noticing he was in possession of a firearm.
He explains, "I took off towards the fight and I completely forgot that as a prop in the film, I was carrying a 357 Magnum. Didn't even think about it, I completely forgot I had it.
"I heard screaming and people started chasing after me. I thought they were joining me to go see what was going on and I had a group of cops and security guards say, 'Whoa, whoa, whoa!' and then I realised I probably shouldn't run towards a fight carrying a big firearm."
