The "Monty" in this song is the the actor Montgomery Clift, who starred in The Misfits
, From Here to Eternity
, and A Place in the Sun
. But unlike other songs about him (see the Clash's "The Right Profile
"), this one doesn't specifically mention his last name, his movies or his pill and alcohol problems. Michael Stipe wrote the lyrics to be more of a contemplation on movies vs. reality.
