Olsen and Bettany enjoyed their '70s sitcom the most. "I loved the '70s because of its absurd, false representation of an aspirational family whilst being pregnant, having contractions, and giving birth," Olsen told Rotten Tomatoes TV. "Because it is the most unrealistic version of a birthing experience one can have. So I enjoyed chewing up that scenery for those moments."
In fact, Olsen accidentally threw in some Lucille Ball in the '70s because there is so much physical comedy, which she said in an interview with Entertainment Weekly was the "most Lucy" she went in this series. That said, she explained how that was the only time Shakman told her she was "too much" and had to dial it back.
Bettany agrees with Olsen, telling Rotten Tomatoes that he loved "playing with those tropes, and Vision getting so excited that Wanda needs to get him to breathe even though she's the one having contractions." In addition to the amazing sets, costumes, and wigs, Bettany also really loved doing the '70s-style title sequence montage, which shows the couple cooking, shopping, and biking in Westview. "It really lent itself to what, it turns out, is Elizabeth Olsen's and my strong suit, which is overacting wildly. Your mugging on the tandem [bicycle] will be a lasting memory for me," he said.
