Mel Brooks had a film staring Gene Wilder in 1968 by the same name. In 2001, the concept was revived as a musical (strangely apt in a way), and has been so incredibly popular it has now been taken to the screen, staring several of the original Broadway cast. (Nathan Lane and Matthew Broderick)
The additions to the musical from the original have improved an already too funny concept. (The blankie is my absolute favorite! You'll know it when you see it.) The songs are fun, and some, especially "Springtime for Hitler" will stick in your mind for a long, long time!
I saw the musical this past summer here at the Dallas Music Hall and was very eager to see it on screen. All the main points were kept. I think my only objection was that the camera would pan in too often, cutting out the full effect of some of the dance sequences. This was a true pity, as otherwise the film was hilarious.
If you want to see something that will have you rolling in the isles - go check this one out! ***3/4!!
