The original 1980 three hour twenty minute unedited version of A Rumor of War and Born On The Fourth Of July are the only two full-length entertainment films known to contain a scene of the M14 type rifle in automatic fire. In 1987, A Rumor of War was re-released as a three part mini-series without the scene of the M14E2 in action. Forrest Gump is the only commercial film known to show the disassembly of the M14 rifle. Two Rock SOPMOD M14 rifles were built for and used in the film Mr. & Mrs. Smith."
