Jonathan Bailey was shooting Bridgerton and Wicked at the same time as Fellow Travelers. In one interview, he stated he once left filming Fellow Travelers and was in a Regency Era costume four hours later. Matt Bomer also said one day, he came to the trailer they shared to see it was shaking. Bomer asked Bailey what he was doing and he was practicing his choreography for Wicked.
Matt Bomer received a Golden Globe nomination for his performance. Many fans were upset that Jonathan Bailey was not also nominated. Matt would later say, "any nomination for me is a nomination for Jonathan Bailey. There is no Hawk without Tim."
While doing press for the show, Matt Bomer and Jonathan Bailey were shocked to find out the bill President Eisenhower signed in 1952, which started the lavender investigation detailed in the show, was not repealed until 2017.
