Montgomery believes that Betty's change of heart is realistic.
"Lewis is just so likable when you see the movie, and people root for him so much, that at the end, when Betty turns and likes him, the audience can believe it," Montgomery says. "Because they know what is attractive in her eyes."
Montgomery says viewers can see her real tears coming down at the end of the film when Lewis makes a speech and the music kicks in. Montgomery was not only sad for the end of the filming, but she also believed in what Lewis was saying.
Director Joe Roth wanted Montgomery to join the group once more for "Revenge of the Nerds II: Nerds in Paradise," in 1987, but Montgomery decided against it.
"I didn't sign on because in the first scene they had Betty cheating on Lewis," Montgomery says. "That was totally out of character."
Roth, who later produced several blockbuster films, told Montgomery to come down anyway and that they would do a re-write.
"But I just felt it was never going to be the character that I wanted it to be," Montgomery says. "I think Betty was forever changed, in a good way, and I didn't want to ruin that."
Montgomery returned for the final two installments of "Nerds," though, as Mrs. Lewis Skolnick. Indeed, the nerd truly did get revenge.
For the last 10 years, Montgomery, 44, has completely focused on growing her family. She hasn't done even one acting job, according to the Internet Movie Database. She lives in California with her husband and children, ages 2 and 4.
"I'm doing all the soccer games and all that stuff," she says. "I just never found the right guy earlier. But I wanted to start a family right away."
Now, her kids can't believe she acted with "Lizzie's Dad", aka Robert Carradine, who played Lewis Skolnick and now stars in "Lizzie McGuire."
But Montgomery has done her share of acting. Even a little skin revealing. She was embarrassed about her nude scenes in "Revenge of the Nerds" when confronting her parents.
"They were upset about it, and we still never talk about it to this day," Montgomery says. "But when you're in your 20s, you think differently."
Now, Montgomery has to make sure her own children don't see her scampering around in a sometimes lustful teenage comedy.
"Oh, I dread that," Montgomery says. "I'm going to have to find it on TV so there are no bad parts."
