Inadvertent comedic effects ensued when John Belushi, in character as Captain Wild Bill Kelso, unintentionally fell off the wing of his airplane, landing on his head. It was a real accident and Belushi was hospitalized for several days, but Spielberg left the shot in the movie as it fit Kelso's eccentric character. During the USO riot scene, when a military police officer is tossed into the window of a restaurant from the fire truck, Belushi plays the patron eating spaghetti. He is in makeup to resemble Marlon Brando in "The Godfather", whom he famously parodied in a sketch on "Saturday Night Live". Belushi told Spielberg he wanted to appear as a second character and the idea struck Spielberg as humorous. At the beginning of the USO riot, one of the uncredited "extras" dressed as a sailor is actor James Caan. Making his first screen appearance in "1941" is Mickey Rourke as Private First Class Reese of Sgt. Tree's tank group. The M3 tank "Lulu Belle" (named after a race horse) and fashioned from a mocked-up tractor, paid homage to its forebear in Humphrey Bogart's 1943 movie "Sahara" where an authentic M3 named "Lulubelle" was prominently featured. Renowned modelmaker Greg Jein worked on the film, and would later use the hull number "NCC-1941" for the starship USS "Bozeman" in the "" episode "". Paul De Rolf choreographed the film.  "1941" is dedicated to the memory of Charlsie Bryant, a longtime script supervisor at Universal Studios. She had served in that capacity on both "Jaws" and "Close Encounters", and would have reprised those duties with this film had she not unexpectedly died. The Oscar-winning team of L.B. Abbott and A.D. Flowers were in charge of the special effects on "1941". The film is widely recognized for its Academy Award-nominated special-effects laden progressive action and camera sequences. The advance teaser trailer for "1941", directed by the film's executive producer/co-story writer John Milius, featured a voice-over by Aykroyd as Belushi lands his plane and gives the audience a pep-talk to join the armed forces, else they will find one morning that "the street signs will be written in Japanese!" The musical score for "1941" was composed and conducted by John Williams. The titular march is used throughout the film and is perhaps the most memorable piece written for it.
