It's hard to believe it's been 21 years since Mrs. Doubtfire hit the big screen, but we have some exciting news for all the fans of the 1993 classic. According to the Hollywood Reporter, FOX 2000 has a follow up in the works! The studio is set to bring back Robin Williams and director Chris Columbus! No word yet on if other original cast members like Sally Fields, Pierce Brosnan and Matthew Lawrence will be joining, but if we had our pick, the flick would be about Robin Williams and that 'ol social worker getting together. We can't wait to see what the sequel has in store!
