Thats a rather vague question, because if you mean animated features like the lion king or Aladdin theyve made 48 with three more on the way.
Live action there into the hundreds maybe even low thousands because they own companies that produce films like Secret Sense, Scary Movie and a lot more than people think.
Also there sequels and Prequels which stand at 25.
then theres Pixar which have made 10 with 4 on the way.
Basically the Disney company is absolutly Massive and my guess is over 500 atleast
