In his new book, Wilmer Valderrama recalled a frightening experience that became a turning point in how he approached his life in Hollywood. “A group of actors and insiders is flying back to Hollywood from New Orleans after the Super Bowl, but nothing is smooth about this flight,” Valderrama, 44, wrote in An American Story: Everyone’s Invited , out Tuesday, September 17. “A winter storm rages across the skies, and the mood on board is shaky.

” Valderrama was “in a small chartered plane” with his That ’70s Show costars Ashton Kutcher and Danny Masterson , as well as Colin Hanks and a handful of other friends. “Outside is nothing but darkness and sleet,” he continued. “The plane is pitching up, down, side to side.

I’m feeling lightheaded. It’s getting hard to breathe. Oxygen masks drop from the ceiling, and I wonder if they dropped because the turbulence shook them loose or if it’s something else.
