Animated films have been popular for as long as films have existed, but what we mean by the term 'animated film' has changed over the years. There's traditional animation - the kind you'll see in 'Bambi,' and there's computer animation of the type you'll see in 'Frozen.' We associate the DreamWorks studio with computer animation, but they once did both. 'Sinbad: Legend of the Seven Seas' changed their mind.
This particular 'Sinbad' film brought in $80m against a budget of $60m, but when you factor in other expenses around the movie, including marketing, it actually translates into a loss. It was one of many such losses DreamWorks incurred during 2003, which saw them finish the year $125m in the red, and having to make drastic changes to their operations going forward. They've never released a traditionally-animated movie since. The only legend we now attach to Sinbad is that he can destroy a movie studio's reputation.
