Ralph Bakshi's animated version of Lord of the Rings from 1978
The Mysterious Cities of Gold (1982)
Not a film per se, but it is worth a mention. It helped popularize the French/Japanese animation style. It also 'mixes in' realistic depictions of nature formations (ie. clouds, video scenery) and other effects for added stylistic realism and immersion. Heavy use of real photographs, art and graphics.
