Studio Dean did a movie adaptation of the UBW route. From my understanding, the movie cuts out alot of stuff, obviously, but went more in detail in some areas than ufotables series. Should watch both.

Currently, in the Fate series of animation, there is;
Fate/ProtoType; The original concept of the Fate series where Saber is a man and the main protagonist is female.
Fate/Stay Night (Studio Deen); The series that kicked everything off. Mostly the Fate route, but contains some of the other two routes as well.
Fate/Stay Night UBW (Studio Deen); As above, has stuff ufotable doesn't have, but lacks.
Fate/Zero; Ufotable's break out show that really showcased what the studio can do. Animation quality, storytelling, everything was really top quality ****.
Fate/Stay Night UBW (Ufotable); Ufotable's adaptation of UBW. People felt it lacked what Zero had, but that's mainly because of source. Zero came from a LN, while Stay Night came from a VN.
Fate/Stay Night Heaven's Feel; Ufotable's third entry into the series, a movie adaptation of the third and final route of the fate series. Not released yet.


and then there's that whole magical girl spin off that you should skip.
