Escape From LA [AKA John Carpenter’s Escape From LA] (1996, dir. John Carpenter)

Snake Plissken is compelled to rescue a gadget from what is now the island prison of Los Angeles. Campy though large-scale reprise of the 1981 predecessor. Some moments work, but this is lesser Carpenter, and a film blighted by woeful CG.

Escape From New York (1981, dir. John Carpenter)

An infamous criminal is sent into the island prison of Manhattan to rescue the US President. Defiantly odd post-apocalyptic piece, much happier with its production design and oddball characters than delivering on action/horror. Not quite the film you remember.
