Outside of Star Trek, he has guest-starred in shows such as Angel, The X-Files and L.A. Law (with Corbin Bernsen). He has also appeared on T.J. Hooker (1983, with William Shatner, James Darren, Richard Herd, Ike Eisenmann and Barbara Harris), Hill Street Blues (with Barbara Bosson and James B. Sikking), Miami Vice, Beverly Hills, 90210, and Charmed. In addition, he had a recurring role on Murder One as Detective Vince Biggoi. This series also starred Star Trek: Deep Space Nine guest star Barbara Bosson and Star Trek: Insurrection actress Donna Murphy.
Clayton has also starred in several TV movies, including Desperate Lives (1982, with William Windom, Viola Stimpson, and Jennifer S. Parsons), The Kid with the 200 I.Q.

In addition, Rohner starred in the 2005 mini series Into the West with Keith Carradine and Garrett Wang.
Clayton starred in the short-lived science fiction TV series E.A.R.T.H. Force in 1990. He later starred in the short-lived USA Network sci-fi series G vs E, later aired on Syfy, as Chandler Smythe. Googy Gress was a regular on the series as well. Rohner apparently really enjoyed doing the G vs E television series. He was so impressed when he read the script to the pilot episode that he agreed to payment of only US$50.00 for his part in the pilot.
Other Trek actors who appeared on the show were Dominic Keating (in two different roles), Mary Mara, Ian Abercrombie, Maury Sterling, Jack Axelrod, Nichelle Nichols, Joseph Fuqua, Robert Costanzo, John Billingsley, Jolene Blalock, Jack Donner, Wade Williams, and Cress Williams.
