This weekend's two-night visit from "Cinematic Titanic" will sadly be the live tour's last, as the riff-happy show is calling it quits at the end of the year. OnMilwaukee caught up with J. Elvis Weinstein (Tom Servo, Dr. Erhardt), Mary Jo Pehl (Pearl Forrester) and Trace Beaulieu (Crow, Dr. Forrester) to talk about why they're calling it a wrap, their "MST3K" days and the most memorably mock-worthy movies in their long, cinematic travels.
