What was Marilyn Monroe's last full length film?

The Misfits is a 1961 American drama film written by Arthur Miller (Monroe's husband at the time), directed by John Huston, and starring Clark Gable, Marilyn Monroe and Montgomery Clift.

The motion picture was the final film appearance for both Gable and Monroe. For Gable, the film was a posthumous release, while Monroe died the following year. The plot centers on a recently divorced woman (Monroe) and her time spent with a cowboy (Gable) and his rodeo-riding friend (Clift) in the Western Nevada desert in the 1960s. The movie was not a commercial success at the time of its release but received positive critical comments for its script and performances and is highly regarded today.

Marilyn always played "dumb blonde" characters. However, the biggest myth is that she was dumb. She had an IQ of 168! This iconic blonde still owns the minds of men and women. Marilyn was found dead at home on the 5th of August, 1962. Marilyn was only 36 years old, and her death was ruled a "probable suicide". Anyway, the details of the tragedy still remain unknown.
