Al Pacino's Looking for Richard

My understanding of this movie is that Pacino had been panned for a stage performance of Richard III, and that the motivation behind this movie was to emphasize the seriousness with which Pacino takes his craft. There were some suggestions that Pacino had thought he might be resting on his laurels to some extent, or otherwise thought he could simply perform Shakespeare as he had any previous role. Making this movie was a clear statement that if his previous performance was not up to snuff, he would demonstrate his willingness to learn and desire to be successful in such a challenging role.

I think the movie seems less self-indulgent if viewed in this light, and it is even more fascinating to watch someone who's as highly regarded as Pacino show so much desire and interest in further perfecting his craft.
