Does anyone remember the name of the movie in which Jason Robards decides he is a tree and plants himself in the front yard, much to his wife's dismay, and starts to grow roots?

Answer 1

MR. SYCAMORE (1975)

IMDB summary:
An unusual but affectionate story of a man's longing for his ideal of peace and serenity. A postman and part-time poet is inspired by the Greek legend of the two elderly guards at Jupiter's temple who are transformed into beautiful trees. His wife has him committed when he stands in his backyard awaiting the same metamorphosis to take place. With the help of a friendly librarian, he escapes in a milk truck during a violent storm.

It has been soooooo long since I have seen that film! I don't think it ever gets aired. I'd love to see this undeniably odd film again. Jason Robards (Jr.) is ALWAYS wonderful! Did you know he's a Jr.? His father was a fine character actor though not as noticeable as his son, who at one time was married to Lauren Bacall. Their son, Sam Robards, is an actor, too. Jason Robards III also is an actor.
