Seltzer's writing credits include the screenplays for The Omen, Prophecy, Six Weeks, My Giant, Dragonfly and Bird on a Wire, starring Mel Gibson and Goldie Hawn. He wrote and directed Lucas (1986), Punchline (1988), Shining Through (1992), and Nobody's Baby (2001).

Seltzer was reported to be writing an "Untitled Earthquake Project" for Hollywood director and producer J. J. Abrams, the plot of which is closely guarded, though it has been confirmed that the film is not a remake of 1974's disaster film Earthquake.^[5] Seltzer is also reportedly working on a UK remake of Alfred Hitchcock's Strangers on a Train, from the novel by Patricia Highsmith.^[6]
