Married couple Marc Guggenheim and Tara Butters have separately written, produced and overseen multiple TV shows. Guggenheim produces Arrow and DC's Legends of Tomorrow on The CW, and Butters was one of the showrunners of Marvel's Agent Carter on ABC. She was also the executive producer of the ABC show Resurrection and Reaper on The CW. They tell us how they met, talk about the experience of working for rival superhero companies, and admit how, in the end, it all comes down to time management.
