It is implied that Gil Hicks and Dante Hicks are cousins.
The 10th Anniversary Edition DVD came out in 2005, but in the Special Features Kevin Smith stated that the DVD was going to be a 5 disc set, but for some reason it was only a double-sided, single disc DVD.
The Extended Version of Mallrats was exclusively released in North America for its tenth anniversary. One has the opportunity to watch a eleven-minute-long video commentary by Kevin Smith (director and screenplay writer) and Scott Mosier (Cutter) explaining the origin of the second version in a very casual and ironical way.
Basically, the Extended Version only contains extended scenes. The alternate footage / takes are usually longer and some comedy have been added. Lots of the extended or alternate scenes are referring to the prolog of the Extended Version , they wouldn't make any sense at all in the Theatrical Version. The entire footage has probably been removed from the Theatrical Version to reach the appropriate length of 90 minutes.
