Easter Parade (1948)
Jesus Christ Superstar (1973)
Two films that could both be described as Easter musicals but very different from each other.
In the documentary on the JCS DVD lyricist Tim Rice says that he would have preferred that the filmmakers had adopted a more realistic approach and I have to say I agree. As it stands, taken literally the film is about a troupe of actors who take a bus to the desert where they put on a production of Jesus Christ Superstar for no one. The weirdest part is at the end when they get back on the bus and Ted Neeley (Jesus) is nowhere to be seen, suggesting that maybe they took the performance a little too far.
That said, if you can get past the framing device it is a solid and moving portrayal of the story.
