Marilyn Monroe tried to prevent herself from spiralling into the depression which eventually led to her suicide by seeking help from acting contemporary Marlon Brando, according to recently unearthed letters. Monroe had planned to establish a production company to protect her from the "quicksand I have always been in" and had attracted interest from the actor, according to letters written to Brando and her acting teacher Lee Strasberg in 1961. In a letter to Strasberg, who also taught James Dean, Robert De Niro and Al Pacino, she wrote: "I have contacted Marlon on the subject... and he seems to be quite interested." In the letter to Brando which has never been made public, Monroe said: "Dear Marlon, I need your opinion about a plan for getting Lee out here on more than a temporary basis. Please phone me as soon as possible. Time is of the essence. Marilyn." Brando replied to Monroe's note with: "Tried to reach you by fone (sic). Must leave the city this weekend. Sorry. Marlon."
