Tom Cruise has literally been around the world during the last few weeks, taking his Mission: Impossible — Ghost Protocol from India to Dubai, then onto Europe, and now, Brazil! He will be in Rio this afternoon for their latest screening, and fans can watch as it happens — here's the link to live-stream the MI4 premiere! In addition to seeing Tom hitting the red carpet, the event will also feature a performance from Tiësto. The fun starts online today at 4 p.m. ET. Tom's travels will bring him home to the US next week, when he brings his latest Ethan Hunt film to the Big Apple.
