No. 13: Oz (1962)
Animation
Unfinished commercial adaptation of L. Frank Baum's The Wonderful Wizard of Oz which was shelved after Smith's close friend, the executive producer and primary financial backer Arthur Young died of cancer. Portions released as No. 16, 19, and 20. From the reported three to six hours of camera test footage (rushes) only ca. 15 minutes, in the form of non-color-corrected rushes, is known to be extant. The only completed bit is The Approach to Emerald City, a 5 (other sources say 9 resp. 12) minute sequence set to music from Charles Gounod's Faust.
