Even though the title is "Bambi II", this film is not an actual follow-up to the first movie; it takes place in the middle of the first film as in between the time Bambi and The Great Prince walk together after Bambi's mother has died and the next spring that starts with the "Little Spring Song."
This movie broke the record of the longest interval between a prequel/midquel/sequel and its predecessor, previously held by The Wizard of Oz (1939) and Return to Oz (1985). Bambi (1942) was released in 1942, Bambi II (2006) in 2006, 64 years later.
The background-paintings were painted with "Corel Photo Paint", but some of the original oil-painting backgrounds from the 1942 original movie were scanned with a computer, and parts of these scans were reused in the new backgrounds.
The film went through several production names. The first was "Bambi and the Great Prince of the Forest", which was its advertised title on the Bambi DVD. The next title was shortened to "Bambi and the Great Prince", then finally, "Bambi II".
