AceShowbiz - Wilmer Valderrama opens up about his experience filming "That '70s Show" with Ashton Kutcher. In his memoir, "An American Story: Everyone's Invited", Valderrama, who played Fez on the beloved sitcom, reflects on the initial audition process and his relationship with Kutcher, who portrayed Michael Kelso.

Valderrama admits that he initially underestimated the show's potential but later embraced it with full commitment. He also reveals that Kutcher, despite his seemingly carefree persona, was a dedicated actor who took his craft seriously.

The duo developed a "friendly rivalry" to see who could elicit the biggest laughs from the audience on the first take. Valderrama explains that the first take often produced the most genuine laughter, and they would often intentionally make mistakes on subsequent takes for entertainment.

Throughout the show's eight seasons, Valderrama and Kutcher, along with the rest of the cast, forged a strong friendship and supported each other both on and off-screen. Valderrama particularly bonded with Laura Prepon, who played Donna Pinciotti, considering her a "sister."

Despite being offered a role in the "That '90s Show" reboot, Valderrama declined due to scheduling conflicts. He expressed respect and support for the new cast members and emphasized that it was their time to continue the legacy of the show.

Valderrama went on to star in other successful projects, including "Naval Criminal Investigative Service", where he continues to showcase his acting talents.
