Seems an odd combination to me, but, two films of superheroness for under a fiver can't be bad.
Born into a world filled with prejudice are children who possess extraordinary and dangerous powers the result of unique genetic mutations. Cyclops unleashes bolts of energy from his eyes. Storm can manipulate the weather at will. Rogue absorbs the life force of anyone she touches. But under the tutelage of Professor Xavier (Patrick Stewart), these and other outcasts learn to harness their powers for the good of mankind. Now they must protect those who fear them as the nefarious Magneto (Ian McKellen), who believes humans and mutants can never co-exist, unveils his sinister plan for the future!
Batman - The Movie.
When Batman (Adam West) and Robin (Burt Ward) get a tip that Commodore Schmidlapp (Reginald Denny) is in danger aboard his yacht, they launch a rescue mission. But the tip is a set up by the four of the most powerful villains ever, who seek to defeat the dynamic duo once and for all! Armed with a dehydrator that can turn humans into dust, this fearsome foursome intend to take over the world! Can the caped crusaders use their high-flying heroism and groovy gadgetry to declaw catwomen (Lee Meriwether), ice the penguin (Burgess Meredith), upstage the joker (Ceasr Romero), and stump the riddler (Frank Gorshin) in time?
