Movies that is shorter... examples

Many classic films were cut in length and edited for reasons the studio executives considered, to improve the film's commercial viability, and to fit in with double bill marketing strategies.


The Wicker Man (1973) was originally a 99 min film but was cut back for marketing reasons to 87 min for it's theatrical release, despite reservations about the affect on the film's continuity, it was released on a double bill with Don't Look Now. 
Director Robin Hardy sought to  restore the narrative structure, some of the erotic elements which had been removed, and a very brief pre-title segment, tracking down the original elements a 96-minute restored version was released in January 1979. 
There are now three versions which recently became available as a set, UK theatrical cut 84 min, The Final Cut 91min and the Director's Cut 99 min
