Whatever else has changed around him, Andrew Patrick Ralston has remained a working actor with the unglamorous consistency that long careers are made of. Counting cinema and television together, the tally passes 37 titles. The most visible line on the filmography is 'Nope' (Tom Bogan / Brett Houston). 'Lethal Weapon' counts among the more visible credits. 23 was the age at the first credit. More of the credits fall under drama than under anything else.
