Before today I had never heard of 18 year old Maciej Musial, nor had I seen his work. I have seen him described as "the Polish Justin Bieber", but that doesn't seem quite right, as Bieber is a singer and Maciej is an actor. Regardless, Maciej seems to be very popular in his native Poland, mostly for his television work, and also, no doubt, because he's a adorable little son-of-a-gun.
Fun fact! He dubs the voice for Billy Unger in the Polish broadcasts of Lab Rats!
Please enjoy this clip of Maciej channeling Tom Cruise in Risky Business.
