Our cameras caught Jake Gyllenhaal when he stopped by Jimmy Kimmel Live to promote his upcoming thriller Prisoners. During the fun-filled interview, the 32-year-old admitted that while he is usually likes to plan things out, in 2011 he impulsively went on tour with the band Mumford & Sons during their Railroad Revival Tour -- and at one point almost got arrested! What?! We didn't know any of this!

"We got stopped by the state troopers at one point in Texas … and I was researching to play a police officer actually and I thought I really knew how to play a police officer at the time, I had done two or three months of research," said Gylenhaal. "I got off and I was like 'Hey guys, don't worry about it …' and they were like get the hell out of here, they were almost about to arrest me. That would have been a good story. "

The Brokeback Mountain star seemed totally at ease during his interview, even mocking Kimmel on his tie selection from the actor's previous visit to the show. While we love the back and forth, we are a little surprised the late night host didn't fire a crack back about the Gyllenhaal's greasy hair! You could run a car on that amount of product -- or at least be in a revival of Grease!

The End of Watch star's newest thriller follows Keller Dover (Hugh Jackman) after his six-year-old daughter and her best friend are kidnapped on Thanksgiving. During the search, Dover butts heads with headstrong detective Loki (Gyllenhaal) who is in charge of the investigation. Eventually the father takes matters into his own hands and takes the man he believes is responsible for the kidnapping (Paul Dano) prisoner and quickly loses control. Prisoners breaks in theaters on Sept. 20.
