Theatrical versions -- The Todd-AO 70mm version and the CinemaScope 35mm version are completely different, with different opening credits, each scene being shot twice and with different sound mixes. In the Todd-AO version, the titles appear against a black background; then, the black background fades out to reveal two rows of giant cornstalks, through which the camera tracks, until it finds Gordon MacRae singing "Oh, What a Beautiful Mornin". In the CinemaScope version, we first see the cornstalks, the camera tracks through them; then, as the words "Rodgers and Hammerstein present" appear on-screen, Gordon MacRae appears and rides up to the camera and then past it off left, as the title "Oklahoma!" appears. The rest of the opening credits in this version are shown against, first, a background of a barn, then, a meadow with a tree nearby. As the credits end, the camera cuts back to MacRae and he begins singing. At the end of the Todd-AO version, we see the words "Distributed by Magna". At the end of the CinemaScope version, we see the words "Distributed by RKO Pictures".
Video versions - Video transfers derived from the CinemaScope version exist both in the traditional pan-and-scan transfer (such as "Rodgers & Hammerstein Silver Anniversary" edition), and a letterbox transfer. Both of these video transfers are available with and without the "Overture", "Entr'Acte" and "Exit Music". Recently, a video in letterbox transfer has been derived from the Todd-AO version, with the "Overture", "Entr'Acte" and "Exit Music".
