Tremblement de terre

The producer, Jennings Lang, offered a cameo role to his friend Walter Matthau. Matthau accepted, without compensation, on the condition that he be billed under the name "Walter Matuschanskayasky," the last name being a long-standing "inside joke" that he had used for decades. The role was originally scripted as "a drunk sits at the end of the bar", which was expanded by writer George Fox, giving the character lines of dialogue (involving toasts to celebrities). When the film was completed - as agreed to by Lang and Matthau - "The Drunk" was credited as "Walter Matuschanskayasky." This led to a long-standing (and false) rumor that "Matuschanskayasky" was Matthau's real last name.

When Miles (Richard Roundtree) drives in and out of the loop on his motorcycle, the stuntman is a White stuntman wearing dark makeup.

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 Stewart 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.
