In 1973, Landau starred in the Columbo episode: Double Shock alongside Peter Falk.
Landau plays twin brothers involved in the murder of their rich uncle.
The episode also costarred Dabney Coleman, Julie Newmar, and Jeanette Nolan.

In the mid-1970s, Landau and Bain returned to TV in the British science-fiction series Space: 1999 (first produced by Gerry Anderson in partnership with Sylvia Anderson, and later by Fred Freiberger).
Critical response to Space: 1999 (also known as Moonbase Alpha) was unenthusiastic during its original run, and it was cancelled after two seasons.
Landau was critical of the scripts and storylines, especially during the series' second season, but praised the cast and crew.
He later wrote forewords to Space: 1999 co-star Barry Morse's theatrical memoir Remember with Advantages (2006) and Jim Smith's critical biography of Tim Burton.
Following Space: 1999, Landau appeared in supporting roles in a number of films and TV series.
He was seen in low-budget genre pictures, such as the science fiction films Without Warning (1981) and The Being (1983) or the horror film Alone in the Dark (1982).
 His roles included the TV film The Harlem Globetrotters on Gilligan's Island (1981), which again co-starred Bain (and marked the final time they appeared together on screen).
