The CBS Late Movie is a CBS television series (later known as CBS Late Night) during the 1970s and 1980s. The program ran in most American television markets from 11:30 p.m. (ET/PT) until 2:30 a.m. or later, on weeknights. A single announcer (in the early years, CBS staff announcer Norm Stevens) voiced the introduction and commercial bumpers for each program, but there was no host per se, or closing credits besides those of the night's presentation. (The bumpers announcing the stars of the movie rotated names, two or three at a time, so more of the players would be mentioned.) The program was launched following the cancellation of The Merv Griffin Show, CBS' late night talk show from 1969 to 1972, which went on to have a long run in first-run syndication following CBS' cancellation. The CBS Late Movie theme music was "So Old, So Young" by CBS West Coast musical director Morton Stevens, which also served as the theme music for CBS' prime time movies until 1978.

However, three years earlier, scheduling coordinators at many of the network's affiliates, who were programming old movies after nightly local newscasts, took notice of the dwindling stock of new films available for acquisition. In fact, a 1966 poll of CBS affiliates revealed that approximately 80% of local outlets were demanding the network "supply a late evening entertainment show Mondays through Fridays" to fill the growing void in newer films. Thus, CBS tentatively targeted the spring of 1968 as the premiere date for a new network late night series. But CBS spokespersons admitted they "did not know whether its show would be similar to others, but it [was] hopeful of devising something different" from the usual talk format exemplified by Johnny Carson's Tonight Show on NBC or Joey Bishop, who was about to bring his own brand of chat to ABC audiences. In 1967, at its annual convention, CBS met with 750 affiliate executives and told them the network could provide a Carson-style late night program by the following spring—but only if 85% of station-owners would commit to airing it. Otherwise, the financing required for such a production would prove cost-prohibitive. No official poll was taken among the executives, however, and this may have been due to the fact that in 1966 when a similar offer was dangled before affiliates, only
