Not sure who Dave Woodman of cinema retro.com is but here is an interesting quote regarding a possible IAMMMMW Box set from Criterion:
When asked if there's anything else he might add, Dave said, "Criterion has hired me to create a map of locations for their box set release of this movie and last night Karen Kramer gave me permission to reveal that the 50th anniversary Cinerama Dome screening of It's a Mad, Mad, Mad, Mad World will take place on October 27th. The Dome itself was built to showcase this movie.".
