Jeff Franklin recalls working with twin sisters Mary-Kate, Ashley Olsen in 'Full House'

Jeff Franklin recently got candid and reminisced about working with twin sisters Ashley Olsen and Mary-Kate Olsen when they were just one year old.

For those unaware, Ashley and Mary-Kate started working on Full House at nine months, portraying Michelle Tanner throughout the eight seasons.

While conversing with PEOPLE magazine, Franklin shared his experience of how it felt working with them on the American television sitcom.

Calling to mind, he said, “There was an episode about Uncle Jesse being an Elvis impersonator, which I happened to direct, which had John’s mom and my mom make little cameos in it. And that was really fun for us.”

“And then that was the show, if you go back and watch it, that was the show where — and I think it was Ashley — it went to entirely another level.”

“For the first time, we had an Olsen twin playing a scene that went on for minutes, and they hit all their cues, played the scene, never looked at the camera, never looked up at the boom, never looked at the audience, stayed in character, hit every joke,” the 71-year-old American screenwriter and director stated.

Franklin stated that whatever happened was completely “insane” and it was something he did not see happen “anywhere else on the planet.”

“It was actually the last show of season one, and I’ll just never forget it. It was just miraculous. How is this possible? In what universe does this little one-year-old person have the audience in the palm of her hand and is hitting jokes? It was just jaw-dropping,” he remarked.

It is pertinent to mention that Full House, which ran from September 1987 to May 1995, had an ensemble cast, including Bob Saget, Candace Cameron, John Stamos, Dave Coulier, Jodie Sweetin, and others.
