Shia LaBeouf gets into some trouble in Vancouver

From TMZ: Last week, while in Vancouver shooting "The Company You Keep," the 25-year-old actor got into an altercation inside a bar and proceeded to take it outside, where he was given a beatdown.

Whatever started the fight inside of Cinema Public House is unclear, but the rumble spilled out onto the sidewalk and culminated in a shirtless man pummeling the "Indiana Jones and the Kingdom of the Crystal Skull" star as he was splayed out on the sidewalk -- a move TMZ caught on video.

Moments after the attack, Shia tries to chase after the guy -- but someone who appears to be his friend holds him back, telling him, "You gotta lay low right now!"

A rep for Cinema Public House tells TMZ, no one on staff noticed the brawl outside -- but the rep confirms ... Shia has been a regular at the place since he's been in town to shoot "The Company You Keep."
