According to Tricia Olszewski (there’s a name easy to google!), Steve Martin insisted that a wedding scene be written into the Pink Panther movie sequel script because “every movie I’ve done that ends in a wedding or holding a baby has been a hit.” A commenter adds:
I once saw a profile of Steve Martin on Comedy Central in which they were interviewing John Cleese, apparently a friend of Martin’s. They asked him why Martin, an avid art collector, frequently agrees to star in movies that are obvious dreck. (Pink Panther, Bowfinger, Bringing Down The House, et. al.) Cleese paused for just a moment and said “Well, works of art are very expensive.”
(P.S. don’t forget to watch the Great Flydini if you haven’t already).
