Tom Cruise has been using an alias he calls his "porn star name" to check in to the fancy U.K. Hotel where he's been staying while shooting his latest movie.  According to the British tabloid "The Sun", Tom has been saying his... amusing alias of "Cage Hunt" is his porn name and has been having a good laugh with hotel staffers and guests while making the movie  "All You Need is Kill".

Tom's alias got me thinking about the names some other Hollywood stars are known to have used when checking in to a hotel or making a restaurant reservation.
