Kurt played "The Professor" in Mil Mascaras vs. the Aztec Mummy and Karen did artwork for the film.
Their daughters were also on set for the first shoot in 2004:
Drennen (left) played the hostess in Mil's opening scene in the film, but sadly her part was left on the cutting room floor. Brighton (right) is shown here behind-the-scenes in 2004.
Brighton ended up playing a prominent role as "Maura" in both Academy of Doom and Aztec Revenge. Below is Brighton behind-the-scenes in 2006 (left) and in 2009 (right).
Below shows Drennen, Kurt, Richard Lynch, and Brighton at the Missouri Capitol during filmming in 2004.
