(written from a Production point of view)
Matt McCoy (born 20 May 1958; age 62) is the actor who portrayed Devinoni Ral in the Star Trek: The Next Generation third season episode "The Price". One of his suits was later worn by actor Neal Kaz in the Star Trek: Voyager fifth season episode "Someone to Watch Over Me" and was sold off on the It's A Wrap! sale and auction on eBay. 
He is probably best known for his appearances as former mental patient Lloyd Braun on the hit television series Seinfeld. That series featured VOY guest actor Jason Alexander as a regular cast member.
McCoy starred as Sergeant Nick Lassard in two Police Academy films, both of which also starred Star Trek: Deep Space Nine and VOY guest actor David Graf. The first was Police Academy 5: Assignment: Miami Beach in 1988, which also featured Rene Auberjonois. That same year, he and Auberjonois co-starred together in an episode of Murder, She Wrote. The following year came Police Academy 6: City Under Siege, which also featured the likes of Kenneth Mars, Arthur Batanides, and Darryl Henriques.
Also in 1989, McCoy had a supporting role in the science fiction film DeepStar Six, along with Miguel Ferrer. He also appeared alongside Armin Shimerman and James Cromwell in the 1990 TV movie Miracle Landing. In 1992, he played a lead character named Michael Bartel in the Curtis Hanson film The Hand That Rocks the Cradle (with John de Lancie) and cast by Junie Lowry-Johnson. His motion picture credits since then have included Hanson's L.A. Confidential (1997), which co-starred James Cromwell, Bob Clendenin, Steve Rankin, Symba Smith, Brenda Bakke, John Mahon, Jim Metzler, and Colin Mitchell, as well as stuntmen Steven Lambert, Don Pulford and Allan Graf; and the 2003 action comedy National Security which also featured Brett Cullen.
McCoy and his L.A. Confidential co-star James Cromwell were among the many Star Trek veterans who were part of the cast of the 1986 mini-series Dream West. The other Trekkers who had roles in this series were F. Murray Abraham, Jeff Allin, Erich Anderson, John Anderson, Lee Bergere, Michael Ensign, Jonathan Frakes, William Glover, Alice Krige, Glenn Morshower, Fritz Weaver, Noble Willingham, and Anthony Zerbe. McCoy and Cromwell later co-starred in the 1990 television movie Miracle Landing – along with Armin Shimerman, Jeff Allin and Herta Ware – and in 2001, they were both regulars on the short-lived television series Citizen Baines.
- There is a humorous moment in Police Academy 5 when McCoy's character, Nick, appears to subdue a thug with a Vulcan neck pinch. Off the others' amazed looks, he holds up a syringe filled with a sedative, giving a Vulcan salute with his other hand.
