why do old movies have credits in the beginning
Opening credits Up until the 1970s, closing credits for films usually listed only a reprise of the cast members with their roles identified, or even simply just said "The End," requiring opening credits to normally contain the details. For instance, the title sequence of the 1968 film Oliver! runs for about three-and-a-half minutes, and while not listing the complete cast, does list nearly all of its technical credits at the beginning of the film, all set against a background of what appear to be, but in fact are not, authentic 19th-century engravings of typical London life. The only credit at film's end is a listing of most of the cast, including cast members not listed at the beginning. These are set against a replay of some of the "'Consider Yourself" sequence.
List of changes in Star Wars re-releases The first film was released in 1977 under the title Star Wars. The subtitles Episode IV and A New Hope were retroactively added to the opening crawl in a subsequent release.[11][12] Accounts differ as to when this change occurred. Some, including Lucasfilm, date the addition to a theatrical re-release on April 10, 1981,[8][11][12] while others place it much earlier at the re-release in July 1978.[13] This change was made to bring the original film in line with the titling of its sequel The Empire Strikes Back, which was released in 1980 with the subtitle Episode V.[8]
