The info at the bottom looks like Helvetica.
As for the rest the _Holy Grail_ has some similarity to some of the "pirate" fonts like Blackmoor http://www.myfonts.com/fonts/itc/blackmoor/ Windlass http://www.myfonts.com/fonts/scriptorium/windlass/ and captain Kidd http://www.myfonts.com/fonts/scriptorium/captain-kidd/

As for the bouncy letters in _ANOTHER FILM COMPLETELY_ you could substitute a font like Schnitzle http://www.myfonts.com/fonts/astigmatic/schnitzle-aoe/
Similar bouncy style letters, but in a narrower width, are found in Rather Jazzy http://www.myfonts.com/fonts/pintassilgo/rather-both/ and Lemon Yellow Sun http://www.myfonts.com/fonts/hanoded/lemon-yellow-sun/

The lettering in _AND NOW! AT LAST!_ has a sort of Looney Tunes style. It would be difficult to create the overlap effect with a font, but Marvin Shadow captures the spirit http://www.myfonts.com/fonts/canadatype/marvin/ For more fonts similar to Marvin go to http://www.identifont.com/find?font=marvin&q=Go and follow the link to _Show more similar fonts_.

For _MONTY PYTHON_ same fonts as previous post plus Thats All Folks Outline Bold, which manages to have an element of overlap http://www.myfonts.com/fonts/comicraft/thats-all-folks/
