Prisoner of Zenda should have much to be proud of: nice music by Henry Mancini, good dual performance by Peter Sellers and gorgeous-looking cinematography and impressive sets and locations.
Unfortunately, all this adds to nothing. The film is as if it were written seriously with the screenwriters assuming that it could be turned into a comedy simply by having Gregory Sierra overact and bulge his eyeballs every now and then and the rest of the cast move about in a humorous way. But it doesn't work that way, even Sellers cannot inject enough comedy into this film(in fact, much unlike Sierra, he is slightly underplaying his roles, which is good).
In the end, one gets the impression that the team had a large amount of money and a good cast, but didn't know what to do with them.
