Rich Heldenfels answers questions from TV viewers.

Q: On “The Big Bang Theory,” as the credits roll there is always an epilogue of sorts. The Nov. 1 show said, “Love like there’s no tomorrow, vote like there is.” How timely is that? Has a book been assembled with the epilogues?

A: You have been noticing the so-called “vanity cards” displaying logos of production companies at the end of shows. While some became famous for their images (the MTM cat, for example), writer-producer Chuck Lorre has used them for observations, thank-yous, social commentary, tidbits about making his shows and other items. One sample, from a 2014 “Big Bang” card: Howard’s starting to throw a baseball was “an outright steal from classic scenes performed by Gleason and Carney (who probably stole it from Laurel and Hardy, who probably stole it from Euripides).” Lorre has done the cards for more than 20 years on “The Big Bang Theory,” “Young Sheldon,” “Mom,” “Mike & Molly,” “Dharma & Greg” and “Two and a Half Men.”

Many of the comments were collected in a limited-edition book, “What Doesn’t Kill Us Makes Us Bitter,” in 2012. Copies of the book can carry a triple-digit price tag now, but you can find the images of all the cards up to the present day, including several censored ones, online in “The Official Vanity Card Archives” on chucklorre.com. Just understand that once you start looking at the cards, it’s hard to stop.

Q: Could you tell me why Paul (Doug Davidson) and Ashley (Eileen Davidson) have apparently left “The Young and the Restless”? And are they related?

A: Doug Davidson said earlier this year that the daytime soap did not renew his contract, ending a 40-year run with the series. According to several reports, he indicated the series was going in a different direction. Eileen Davidson (no relation, by the way) decided to leave the series after 36 years. She told Michael Fairman in a YouTube interview that there were many reasons for her decision, among them the long workdays, the hours commuting and missing her family while working.

Q: How many Oscar winners have had their own TV shows?

A: Would you believe dozens? While there was a time when a major movie was thought as higher status than a TV role, even acclaimed actors have long gone to whichever form offered work. In fact, we can break the Oscar/TV names into categories: people who won Oscars and then did TV, people who were TV actors and went on to win Oscars, and even some who won Oscars while working in TV.

That last category includes three winners of supporting actress Oscars: Allison Janney, who won for “I, Tonya,” while starring on “Mom,” Viola Davis, with “Fences” and “How to Get Away With Murder,” and Patricia Arquette, who won her Oscar for “Boyhood” about two weeks before her series “CSI: Cyber” premiered.

Another supporting actress winner, Lee Grant in “Shampoo,” picked up her Oscar about five months after her short-lived sitcom “Fay” was taken off the air. NBC showed some leftover episodes after Grant’s Oscar win.

As for Oscar winners who afterward had TV series, the long list goes back at least 65 years, when Loretta Young hosted an anthology drama and goes on to Walter Brennan, Shirley Booth, Donna Reed, Anthony Quinn, Shirley Jones, Broderick Crawford, Patty Duke, Cloris Leachman, Timothy Hutton, Marlee Matlin, Mary Steenburgen, Dorothy Malone, Maggie Smith, Anna Paquin, Reese Witherspoon and Whoopi Goldberg, among others.

People who were famous first on TV and then won Oscars include Sally Field, George Clooney, Art Carney, Martin Landau, Robin Williams, Jamie Foxx, Mo’nique, Melissa Leo, Denzel Washington, Red Buttons, Lee Marvin and Henry Fonda. (Fonda was, of course, one of our greatest actors, but he did not win an Oscar until shortly before his death in 1982, and he’d starred in several TV series before then.)

Q: Was I the only one who was surprised at the departure of Monica Dawson from “Chicago Fire”? Why did she leave — salary dispute, contract was up?

A: Monica Raymund, who played Gabby Dawson on the NBC drama, was at the end of her contract when she decided not to stay with the show. In one published interview, she said, “I felt like I was hungry to explore a different role, a different story. I wanted to explore a different world. I had been in Chicago for five years and just personally where I was in my life, I was ready to create my home and kind of plant some roots in Los Angeles. … it’s wonderful to be employed for that long and to have job security. … But sometimes you have to take a risk to diversify your opportunities."
