DVD Talk mentions that Eric makes an appearance in one of the deleted scenes of Elektra Luxx, an R-rated comedy by Sebastian Gutierrez, starring Carla Gugino and Joseph Gordon-Levitt, which has been released on DVD today (Amazon link).
“Deleted Scenes” (18:44) offer a lackluster interview between Bert and a dim-witted pornstar, a moment of aborted intimacy between two supporting characters, and follows jittery personalities played by Eric Stoltz and Lucy Punch as they negotiate their first three-way.
