I've been featuring a lot of cheese on the blog lately. This film is no exception - in fact, this film is an exemplary specimen of ripe, pungent, aromatic cheese, courtesy of Aaron Spelling. After flight 502 for London takes off from New York, a letter is discovered in the first class lounge warning of murders that will take place during the flight. Only the first class passengers are involved, and they include mystery writer Mona Briarly (Bergan), pop star Jack Marshall (Bono), international thief Paul Barons (Fernando Lamas), Jewish mother Ida Goldman (Molly Picon), bratty teenager Millard Kensington (Danny Bonaduce), Charlie Parkins (Walter Pidgeon) as well as a flight crew including Captain Larkin (Robert Stack) and stewardess Karen White (Fawcett). Who is responsible for the letter and who is or are the targets? As people start to die (in the "yanked from view into a closet" style of murder) we learn that the person who wrote the letter isn't joking. Red herrings abound, are dismissed and then the characters involved in them are relegated to the background. Also look for Brook Adams, Laraine Day, Ralph Bellamy and Hugh O'Brian in the cast.
Due to Farrah Fawcett's involvement in the film, it was released on DVD in the late 90's. Most of the reviews I've read seem to have missed the campier aspects of the film, but it's worth seeing for just those aspects. In addition to DVD, it can be seen in full above, thanks to a YouTube upload by smpr12.
