The Last Action Hero made a guest appearance on the opening day of Baselworld 2012, the biggest watch fair on Earth, looking fully recovered from his recent shoulder surgery (and bed-in with Sylvester Stallone). Guess he fancied doing a bit of shopping.
There are two theories at work here. A) Arnold doesn't quite understand what the purpose of a commentary track is, or B) He is actually narrating Total Recall for blind people. Either way, it's friggin' hilarious.
