As a bad movie aficionado, I'd like to suggest five films for consideration in HDTGM:
1. Hellraiser 4: Bloodline - Even though there are worse Hellraiser films (Deader and Revelations being the worst), this is the only Hellraiser film featuring Earwolf regular and blockbuster movie actor Adam Scott! Also the first entry in the series to enter the genre-coffin of Space, this was the last entry to go theatrical before producers started buying spec scripts and adding pinhead to them.
2. Dylan Dog: Dead of Night - To say this film has the effects of a student film would be a disgrace to student films. With the budget of most run-of-the-mill action films and a cast that includes Peter Stormare and Taye Diggs, you also get hammy, stiff dialogue and pro wrestler Kurt Angle in a werewolf mask.
3. Legion - A post apocalyptic film where the man insinuated to be the new jesus Christ is named Jeep Hanson. Also features Demon Grandma, Machine Guns and slow-motion angel fights.
4. Freaked - Truly an insane, awesome irreverent film that makes no sense and all the sense at the same time. Alex Winter would also be a great guest and has embraced the cult nature of this film.
5. Wild At Heart - David Lynch and Nicolas Cage. Why hasn't this been done already? Another movie that I absolutely love but needs to be dissected for how absolutely insane it is.
