There is many more movien this, but included only the biggest movie serues on these three. 20th century Fox has also Fantastic 4, Daredevil, Elektra, Blade and many other, but X-men is the movie series they have had most focus on and many more movies of. But this will change now in the near future since Marvel's deal with Fox has recrntly been finished now, that means that they now have rights on making movies og their characters. Same with Spider-man from Sony that Marvel got in 2016 in Captain America: Civil war.
