NEW YORK, N.Y. – Betsy Brandt says the intensity of the final “Breaking Bad” episodes “physically affected” her.

“There were days shooting — these last eight episodes especially — I just felt sick. My chest would get all tight and I just felt awful,” she said.

Brandt plays Marie Schrader, sister-in-law to chemistry teacher turned drug lord Walter White (Bryan Cranston) on the show, which airs its series finale this Sunday on AMC at 9 p.m. EDT. In an interview Wednesday she said she did a lot of crying, too.

“After we’d get a take then I’d just sort of start sobbing because you gotta get it out before you go home,” she said.

The actress says the weightiness of “Breaking Bad” had a lot to do with her decision to take on the comedy “The Michael J. Fox” show as her next role. She plays Annie Henry, wife of Fox’s character in the series that premieres Thursday at 9 p.m. EDT.

Brandt says when she read the “Breaking Bad” finale script, she told show creator Vince Gilligan it was “the perfect ending for this show.”

She’s not giving out any hints, not that people really want to know.

“It’s funny. They want me to tell but they really don’t want me to tell,” Brandt said. “People are crazy, ‘Tell me. Don’t tell me. Tell me. Don’t. No. Please stop.’ That’s kind of what it is.”
