I Love Lucy Head-writer/Producer Jess Oppenheimer on Dress Rehearsals:
“Everyone would stay for this, even the stage hands. They were wonderful sessions where we’d even get into the philosophy of the script. We’d have our share of arguments, too. Bill Frawley (Fred Mertz) would get his back up over the way he wanted to read a line or something. But they were very stimulating and fruitful. We really dug into the characters because we took these people very seriously and tried to make everything logical.”
