(written from a Production point of view)
Actor Jonathan Ray Banks (born 31 January 1947; age 74) played Golin Shel-la in the Star Trek: Deep Space Nine first season episode "Battle Lines". Rick Berman was impressed with Banks' performance in the episode, commenting that he "did a nice job". David Livingston thought that Banks "did a terrific job" in the episode. (The Deep Space Log Book: A First Season Companion, p. 75 & 76)
He is best known for his Emmy-nominated role in the TV series Wiseguy from 1987 through 1990 and as Mike Ehrmantraut on AMC's Breaking Bad and its spinoff, Better Call Saul, also featuring Raymond Cruz, Patrick Fabian, Mark Margolis, Ann Cusack, Ethan Phillips, Ed Begley, Jr., and Michael McKean. Banks' first appearance on Breaking Bad was in the 2009 episode "ABQ", when his character is sent to "clean up" evidence after the girlfriend of one of the main characters overdoses. The girl's father was played by John de Lancie. Audience response was so strong that Banks' role was expanded to that of supporting character. In 2011, Breaking Bad was nominated for a Screen Actors Guild award for Outstanding Performance by an Ensemble in a Drama Series category.
On 16 July 2015, Banks received an Emmy Award nomination for his role as Ehrmantraut in Better Call Saul. 
Banks also appeared in the films Airplane! (1980, with Gregory Itzin, Kenneth Tobey and Jason Wingreen), 48 Hrs (1982, with Denise Crosby and Margot Rose), Gremlins (1984, with Zach Galligan, Dick Miller, Keye Luke, and William Schallert, and music by Jerry Goldsmith), Beverly Hills Cop (also 1984, with Steven Berkoff, Michael Champion, Ronny Cox and Douglas Warhit), Freejack (1992, with Mike Starr) and Crocodile Dundee in Los Angeles (2001, with John Billingsley, Kaitlin Hopkins, and Matt Winston). Due to his appearance in Beverly Hills Cop, Banks once again worked for producer Jerry Bruckheimer on the series CSI: Crime Scene Investigation playing mobster Bobby Jensen in 2004 and 2006 in the fifth and sixth seasons respectively appearing in the episodes "Formalities" and "Kiss Kiss Bye Bye," both times working with Star Trek: Voyager guest star Wallace Langham.
