I had heard that Jason is filming a movie about WWII. He probably has the mustache for the role he is playing. I do not think he would just grow that for no reason. At least I don’t think he would. He does kinda look like a general or something like that. Take away that mustache and he looks great. I mean, he looks fine with it too. But, it is nice to know that it is only for a role he is playing. As soon as he is done filming I am sure we will see it go bye bye.
