Debra Winger moved away from the big screen to play Ashton Kutcher's mom on the Netflix series, The Ranch, and she opened up to ET about the surprising role.

After being one of the most sought after actresses of the '80s, earning four Golden Globe nominations and three Oscar nods, the film veteran explained to ET why she made the jump to an old-fashioned sitcom.

"I hadn't done it before," Winger said simply.

On the show, Kutcher plays Colt Bennett, a former high-school football star who returns home after an unsuccessful run as a semi-pro football player. Sam Elliott stars as Kutcher's stern, laconic rancher father, and Danny Masterson, who co-starred with Kutcher on That '70s Show, plays his ne'er-do-well brother.

Winger's character is a straight-talking, no-nonsense-taking mother of two -- a far cry from the bashful starlet ET met in 1982 when we first interviewed the star. During the throwback sit-down, Winger opened up about the nerves she felt before shooting a nude scene for An Officer and a Gentleman, for which she received an Academy Award nomination.

"It was hard for me to do just because I was embarrassed," Winger said at the time. "I kept chipping away at the crew: 'Yeah, we don't need lights. The camera? Just turn it on and leave.'"

Kutcher and Masterson teased their onscreen reunion with fellow '70s Show alums, Wilmer Valderrama and Kutcher's wife Mila Kunis earlier this week at a special screening of the series. Watch the video below to see the gathering.
