Kenneth Mars
Kenneth Mars  was the veteran comic actor and voice actor who played the role of Colyus in the  second season episode . 

Hailing from Chicago, Illinois, he was known for his roles in the Mel Brooks films The Producers and Young Frankenstein and for playing Otto Mannkusser on the TV series Malcolm in the Middle. He was also known for voicing King Triton in Disney's 1989 film The Little Mermaid.

Film work 
A veteran of farcical comedy, Mars was perhaps best recognized for his zany, over-the-top performances in two of Mel Brooks' most well-known films, The Producers in 1968 and Young Frankenstein in 1974. In the former, he portrayed Franz Liebkind, the Nazi playwright of Springtime for Hitler; in the latter, he played Inspector Kemp, a police officer with a creaky wooden arm, a monocle over an eye patch, and an absurd German accent. Mars' co-stars in Young Frankenstein included one-time TOS guest actress Terri Garr. 

His comedic talents were also utilized by director Peter Bogdanovich for his films What's Up, Doc? (1972, with Stefan Gierasch, Graham Jarvis, and Sean Morgan) and Illegally Yours (1988, with Leon Rippy). He was additionally directed by filmmaker Woody Allen in two comedies, 1987's Radio Days and 1991's Shadows and Fog. Both of these films co-starred Robert Joy and Wallace Shawn, while Mike Starr appeared in the former and Richard Riehle, Camille Saviola, Kurtwood Smith, and David Ogden Stiers had roles in the latter.

Mars played many dramatic roles, as well. He had a supporting role as a marshal in the acclaimed, Academy Award-winning 1969 western adventure Butch Cassidy and the Sundance Kid, along with Ted Cassidy, Jeff Corey, Charles Dierkop, and Don Keefer. He then had the lead male role in the 1971 drama Desperate Characters, in which he and Shirley MacLaine play a middle-aged, middle class, childless Brooklyn couple trapped in a loveless marriage. Mars afterward landed roles in a pair of thrillers; the first was 1974's The Parallax View, which also featured an uncredited performance by  actor Anthony Zerbe. The following year, Mars co-starred in Night Moves with Harris Yulin.

Despite his dramatic film work, Mars maintained a propensity for comedic roles. Some of his other comedic films in addition to those with Brooks, Bogdanovich, and Allen include 1969's The April Fools (with Sally Kellerman), 1979's The Apple Dumpling Gang Rides Again (directed by Vincent McEveety and co-starring Ted Gehring, Ed McCready, Robert Pine, and Nick Ramus), 1983's Yellowbeard (with production designed by Joseph R. Jennings), and 1984's Protocol (with Ed Begley, Jr., Joel Brooks, Cliff DeYoung, Jeanne Mori, Chris Sarandon, Gail Strickland, Keith Szarabajka, George D. Wallace, and Paul Willson). He also had a supporting role in the hit 1985 comic thriler Fletch, in which he worked with Bruce French and fellow DS9 guest actor Richard Libertini.

He later appeared in 1989's Police Academy 6: City Under Siege, along with Arthur Batanides, David Graf, Gerrit Graham, Darryl Henriques, and Matt McCoy. Mars again worked with David Graf, as well as the aforementioned Kurtwood Smith, in the 1996 comic drama Citizen Ruth. Mars and Kurtwood again appeared together in the 2002 comedy Teddy Bears' Picnic, which also featured Henry Gibson, Michael McKean, Robert Mandan, and Brenda Strong. This was Mars' final feature film.
