Which film concerns Hal Mohr as the only person to win an Oscar (write-in) without being nominated?

Hal Mohr, A.S.C. was a famed movie cinematographer. He is known for his Oscar-winning work on the 1935 film, "A Midsummer Night's Dream". During the 8th Annual Academy Awards in March 1936, which were presented at the Biltmore Hotel in a ceremony presided over by Frank Capra, Mohr became the only person to win a competitive Academy Award without being nominated for it. In a write-in campaign, he won the Best Cinematography Oscar, "A Midsummer Night's Dream".

In the classic screen adaptation of Shakespeare's fantastical play, the royal wedding plans of Theseus, the duke of Athens (Ian Hunter) and Hippolyta overlap with the antics of forest fairies, led by Oberon and Titania, and a ragtag troupe of actors. Meanwhile, young lovers, including Lysander (Dick Powell) and Hermia (Olivia de Havilland), deceive each other in amusing ways. Also magic adds a mischievous element to this enchanted romantic comedy, "A Midsummer Night's Dream".

Also, regarding Oscar Awards, the Academy changed the Oscar rules, making write-in voting impossible after 1936. In 1944, Mohr became the first person to win an Oscar for both Black-and-White and Color cinematography when he won his second Academy Award. This time, with W. Howard Greene, the Oscar for Best Cinematography in a Color Film was awarded to the two men for their work on "The Phantom of the Opera" (1943). In 1953, Mohr would again be nominated for an Academy Award for Best Cinematographer for his work on "The Four Poster" (1952).
