He wrote a few feature screenplays -Planet of the Apes, 7 Days in May, Assault on a Queen and Requiem for a Heavyweight-but Rod saw himself primarily as a writer not as a producer or director. Feature films take forever to get made and then there are endless revisions and re-writes so he preferred the immediacy (and control) of TV. He thought very highly of TV and its 5b4importance in the 50s to mid 60s but became disillusioned with it because it didn't want to tackle social issues any longer (in his opinion).
