The doctor who comes to the Graff house in the deleted scene is Jim Vance, the doctor who later examines people (like Sam Royce) at the Wilson Plaza. It is revealed that he is a friend of the Graff's and Stewart learns that a baby that they were to have a year ago was aborted by Vance at the request of Remy (Stewart was told it was a miscarriage. The dialogue for this scene and many other deleted scenes are available (with pictures) at EarthquakeMovie.com.
For the initial network television showing broadcast on NBC in September 1976, additional footage was shot to lengthen the film in order to show it over two nights. The most extensive segment of new footage is a subplot of a newlywed couple (Debralee Scott and Sam Chew Jr.) on a flight to Los Angleles so the husband can interview for a job with Stuart Graff (Charlton Heston). The plane tries to land as the earthquake hits, but the pilots are able to regain control and fly away before the runway breaks up. Other significant segments are new scenes with Jody (Marjoe Gortner) and Rosa (Victoria Principal), which establish Jody's obsession with Rosa, as well as one short scene in a pawn shop with Buck (Jesse Vint) and Hank (Michael Richardson), who play Marjoe's roommates in the theatrical version. Contrary to popular belief, these additional scenes were *not* "leftover" footage from the original 1974 theatrical release. Rather, the footage was filmed almost two years later by NBC to expand the film. These additional scenes were shot without the original director Mark Robson, who opted out, (in fact, he loathed the additional scenes), but they were shot with Universal's approval. In addition, two deleted scenes originally shot for the theatrical release were re-inserted into the television version, including a narrative opening about the San Andreas Fault, as well as a scene of Rosa brushing off a guy (Reb Brown) trying to give her a ride on his motorcycle. Incidentally, the version frequently running on the American cable channel "American Movie Classics" is the television version, and not the original theatrical version.
