When you think about it, the concept behind Mamma Mia is a little strange. It's a fictitious story that is told through ABBA music, after all. But it isn't the only member of its weird little sub-genre of musical, which I'll call a One Band Musical, or OBM for short (not to be confused with the OMB, although I hear Jacob Lew has a lovely singing voice). The first OBM was probably Yellow Submarine, which featured the music of The Beatles. Which leads to the other movie I want to talk about, the prominent and somewhat polarizing 2007 film that also features The Beatles music, Across the Universe.
