I think St. Vincent is really going to depend on Bill Murray in a way that not a lot of movies have had to depend on Bill Murray lately. Murray has become a cameo artist, the kind of actor who just floats in and out of movies, improving pieces of them before disappearing. The last two movies to really star Bill Murray were Broken Flowers and The Life Aquatic with Steve Zissou, which came out almost a decade ago. (I don't include Hyde Park on Hudson, because that was barely a movie at all.) Can he still do it? Is he still able to maintain a character for more than 25 minutes of screen time? What do you think?
