His memorable roles include the invalid Frederick Fairlie in the 1948 film The Woman in White and the pacifist Ayelborne in the Star Trek episode "Errand of Mercy". He also played Sesmar in an episode of Lost in Space, "The Dream Monster", in 1966. He had two siblings - a sister, Ivy Skeates of Cambridge, and a brother, Harold Kefford. and ended up living there for the rest of his life.
On American television between the 1950s and 1970s, Abbott had roles on a wide variety of series such as Kraft Television Theatre, Studio 57, Gunsmoke (lead character Edward Vanderman in S5E20’s The Tragedian” - 1960), Matinee Theatre, Bonanza, Thriller, Star Trek, Mannix, Iron Horse, and Bewitched. Although he was blacklisted during the Red Scare of the 1950s, a producer who wanted to hire him eventually succeeded in getting the actor removed from the list. In his last years, Abbott taught acting to students free of charge.

Abbott died at Cedars-Sinai Medical Center from natural causes on 24 May 1996 at the age of 90.
