"The Fault In Our Star Wars"

From imdb and imdb:

Part IV in George Lucas' epic, the film opens with a cancer support group being attacked by the tyrannical Darth Vader (David Prowse).

The plot then follows the life of two teenagers, Hazel (Shailene Woodley) and Gus (Ansel Elgort), who share an acerbic wit, a disdain for the conventional, and a love that sweeps them on a journey with their newly met allies (Han Solo, Chewbacca, Obi-Wan Kenobi, C-3PO, R2-D2).

Their attempt to rescue a Rebel leader, Princess Leia (Carrie Fisher), from the clutches of the Empire is all the more miraculous given that Hazel's other constant companion is an oxygen tank.

The conclusion is culminated as Gus makes an attack on the Empire's most powerful and ominous weapon, the Death Star, with his prosthetic leg.
