It was common practice for studios to cut some of these epics for general release in order for theaters to book more showings a day and present the film at reduced "popular prices", especially if the film ran longer than two hours. Sometimes this was done to a successful film, such as "South Pacific", but more often to one that had been a notable flop, in an effort to make it a success on its second run. As a result, some of these films have not been seen in their entirety since their first release, as the original edited footage is either missing or no longer exists. With the work of film preservationists and restoration, such roadshow flops as "A Midsummer Night's Dream" (1935), "Mourning Becomes Electra" (1947), "Joan of Arc" (1948), " A Star Is Born" (1954) and "Fantasia" (1940), along with the hugely successful films "For Whom the Bell Tolls" (1943), "Spartacus", "Lawrence of Arabia", "Around the World in 80 Days" and "It's a Mad Mad Mad Mad World", all of which had significant footage missing, have been restored in recent years to match the filmmakers' original intent. However, several extremely popular long films, such as "Gone With the Wind" and "The Ten Commandments", have never been released in edited form, and were nearly always shown on a two performance-a-day basis.
