It is usually a good thing to know that actors had a good time filming a movie. If the movie is a comedy, their natural glee will make their performances that much more believable.
If the actors are good friends with each other, their chemistry will bring out the best in each other’s performances even if the movie isn’t a comedy.
However, it is a bad thing that Johnny Depp and Angelina Jolie had fun filming “The Tourist,” because there is no reason for “The Tourist” to exist other than for Depp and Jolie to have fun.
“The Tourist” is another one of those dreadful “Actors’ Paid Vacation” movies. 2004’s “Ocean’s Twelve” is probably the most well-known example of this formula, but it might soon be replaced with “The Tourist.”
APV movies happen when big name actors want to take a break from their busy schedules. They sign on to do an easy movie in a beautiful location (in this case Venice). Nobody else can book them during this time because they are technically working. They get to spend a few weeks having fun goofing around on a set, and the studio is OK with this because they get to promote a movie with an exotic location and big name actors. Everybody wins, except the people who pay to see a movie that was made just so the actors could enjoy themselves and not because it actually deserved to be made.
