Nicolas Cage Returns to Work -- Like Nothing Happened

UPDATE 4:00 PM PST: Check out this photo of Cage chillin' on the set just 30 minutes ago ... smoking a cigar and going over his lines. What arrest?

Nic Cage
didn't let his drunken arrest keep him from being at work on time this morning ... TMZ has learned the actor was on his movie set and ready to go when the director yelled, "Action!"

A rep for the film, "Medallion" tells us production on the flick has NOT been "affected in any way" because of Cage's sloppy domestic violence arrest early Saturday morning ... and today, things seemed "completely normal."

We're guessing Cage will try to take it easy during the next 6 weeks of shooting ... maybe a couple of quiet nights at home ... if he can remember the address.
