Cockneys vs Zombies – “Shaun of the Dead,” wanna-be, but still lotsa fun, the highlight being an elderly Brit asleep in his lawn chair while the Zs shamble all around him, not realizing he isn’t dead. Then he wakes up and makes a break for it – at 0.0005 MPH – with his walker with a walker in hot pursuit (not). One of the female leads was on, “Doctor Who.” Worth a look.

Several of the episodes of the animated series The Tick has “versus” titles.
My favorites were The Tick vs. The Tick (The Tick fights another superhero who wants to use the name “The Tick”) and The Tick vs. Arthur’s Bank Account.
Can’t believe I forgot the non-classic Neutron vs. the Death Robots (1962). In the same series was Neutrón Contra El Criminal Sádico a.k.a. Neutron vs. the Maniac (1964).
The German semi-classic “Theo gegen den Rest der Welt” translates to “Theo vs. the rest of the world”. I doubt it ever had an official English title, so I hope it counts.
