‘Little House on the Prairie’ star says brutal filming conditions left cast members unconscious

The cast of " Little House on the Prairie " is opening up about the brutal reality of filming the hit TV series.

Cast members were guests on Patrick Labyorteaux's podcast to discuss their experiences on the show.

He asked Alison Arngrim, who starred as Nellie Oleson, what the first day was like for her.

"Complete chaos and confusion," Arngrim admitted. ‘LITTLE HOUSE ON THE PRAIRIE’ STAR SAYS CHILD ACTORS GET ‘DROPPED’ AFTER HOLLYWOOD FAME FADES She explained that she hadn't known she was supposed to show up with her character's signature ringlet curls, "So it was lots of panic and phone calls back and forth, and then massive curling of my hair.

So yeah, bananas.

And then, first day on location, of course, I pass out." "So, I was off to just a rousing start right there," she added.

The conversation also included fellow cast members Dean Butler, Pamela Roylance and Jennifer Donati, as well as Tracy and Victor French, the children of late cast member Victor French.

Labyorteaux also starred in "Little House on the Prairie" as Andy Garvey.

During a later conversation about how hot it was in Simi Valley, where the show was filmed, Arngrim joked that the cast and crew were able to tell when summer hit because the "first day of summer is when Alison hits the ground, because I was out like that.

It was that hot." LIKE WHAT YOU'RE READING?

"It's like basically how to not pass out was the challenge," she continued.

"It was insane, though – the great thing is that other people began to pass out, so people realized it wasn't me, the first one being Sean Penn ." Penn, who was a child at the time, "didn't wake up and come back to work.

That was it, he was done for the day."

Later in the podcast, the subject of their least favorite episodes came up, and Arngrim shared that she disliked any episodes where sporting events were involved, because that meant sitting in bleachers "where it was 100 million degrees" for hours at a time while crew members filmed reaction shots.

She recalled one of these shoots when Charlotte Stewart, who played school teacher Eva Beadle Simms, "was just sitting there, and she had in fact lost consciousness and fainted and blacked out, but just didn't fall over, and they didn't know she was out." About the sweltering set, Butler admitted, "You just had to do whatever strategy you could.
