Looking for a Big Security Guard for a Bit

Looking for a tall/intimidating security guard type for a YouTube social experiment/prank shoot. The scene takes place in an art gallery with a fake sculpture that appears to get knocked over. Your role would be to enter the scene as security and question nearby people to see whether they “snitch” on the person responsible or stay quiet after witnessing it happen. This is a lighthearted filmed bit for YouTube. Acting/improv experience is a plus, but not required. Strong presence and confidence on camera preferred.
