I saw "The World's End" not long ago. Coupled with "Cockney's and Zombies" the makings of a good double feature are there, assuming the latter is any good...
Very funny! I really love these kind of films..but I have to say my all time favorite is Gorgo..totally destroyed London. She was just a mamma monster wanting her kid back who was abducted by money-hungry humans. What a mistake that was!
