At the premiere of The Buccaneer, the announcer calls special attention to Anthony Quinn's bit part. In 1938, Quinn was a little-known 23-year-old at the start of his career, and his presence in that film would only be of widespread interest looking back a few decades later.
The film opens at a sightseeing/tourist spot and parking area at the foot of the "H" in the Hollywoodland sign. No such facility has ever existed as that part of the hill is too steep for road construction. The real road passes behind the sign and above it.
