Too Many Suspects (1975)

When a high fashion designer (Nancy Kovack) is murdered, her married lover (Ray Milland) is the main suspect since she was killed by his gun. But a writer (Jim Hutton), the son of a police detective (David Wayne), is not convinced of his guilt. Based on the novel THE FOURTH SIDE OF THE TRIANGLE by Ellery Queen (a pseudonym for the writing team of Frederic Dannay and Manfred Bennington Lee) and directed by David Greene (GRAY LADY DOWN). In the 1970s, it was common for networks to make a television movie as a potential pilot for a TV series. This telefilm aired in March of 1975 and in November of the same year, the ELLERY QUEEN MYSTERIES aired for one season. I'm a huge fan of whodunits so I'm partial to stuff like this and if you're a fan of the genre, you'll probably enjoy it. I thought it was unnecessarily overlong. For example, when all the suspects are gathered in a TV studio so the killer can be revealed, we sit through an entire recreation of a TV news show instead of going directly to the clue on the show that breaks the case but I guess they had to stretch it out to feature length. The score is by Elmer Bernstein. With Kim Hunter, Monte Markham, Gail Strickland, Warren Berlinger and Tim O'Connor.
