Jonathan Ray Banks (born January 31, 1947) is an American actor.

From an interview with MensJournal.com:

How does one live a happy life?
Keep believing in yourself until the day you die. If you’re not a liar and you’re trying to lead a decent life, then you’ve got to give yourself credit. I put my head on the pillow at the end of the day and tell myself: “You know what, Johnny Banks? Sleep well. You’re doing the best you know how. Maybe you can do better tomorrow. Just try.”

Any thoughts on retiring?
If I leave acting, I’ll just go. No goodbye. I have huge respect for guys who did that: Gene Hackman, Sean Connery. When William Powell stopped, he stopped. Moved to Palm Springs without fanfare. I like the strength of doing that. My work is my work. My ego is something else. And I would like to not have such a large ego that I need to advertise it.

From an interview with AwardsFocus.com:

AF: In terms of Mike’s marksmanship, are you someone who visits the gun range on occasion? Have you had weapons training over the years?

Banks: I’ve had a minimal amount of training, I do like to look like I know what I’m doing (laughs). I have one friend who was indeed a sniper, and my performance passed his inspection so I’m grateful.
