Movie Goofs

They only tell a few of the goofs here but after watching it in the first 4:09 min. i have found a few other issues. First when Danny is dancing in front of Grauman's Chinese Theatre and you see the foot and hand prints of the stars the first one is of Gene Kelly, the date reads 5-8-39 and the date of the scene is 4-12-39. So yeah, that is a month later than the date of the movie scene. Not only that but its not even the correct date at all. Gene Kelly gets his foot and hand print done on 11-24-69. Next is another date, which reads 3-22-59, twenty years after the time of the scene. However, Clark Gable's date is correct. (1-20-37) Here's the link to the site were I got the correct dates. http://en.wikipedia.org/wiki/Grauman%27s_Chinese_Theatre
