After High Rollers was cancelled in 1980, Trebek moved on to Battlestars for NBC. The series debuted in October 1981, and was cancelled in April 1982 after only six months on the air. In September 1981 Trebek took the helm of the syndicated Pitfall, which taped in Vancouver and forced him to commute, as he had done while hosting High Rollers and The $128,000 Question in 1978. Pitfall was cancelled after its production company, Catalena Productions, went bankrupt. As a result, he was never paid for that series. After both series ended, Trebek hosted a revival of Battlestars called The New Battlestars that ended after thirteen weeks, then shot a series of pilots for other series for producers Merrill Heatter, for whom he had worked hosting High Rollers and Battlestars, and Merv Griffin. The Heatter pilots were Malcolm, an NBC-ordered pilot featuring Trebek with an animated character as his co-host, and Lucky Numbers, an attempt at a revival of High Rollers that failed to sell. For Griffin, he shot two pilots for a revival of Jeopardy! when original host Art Fleming (a friend of Trebek's) declined to return to the role due to creative differences. This revival sold; Trebek began hosting the revival in 1984 and has hosted ever since.
