The pair reportedly met when Galvin took over the lead role in Broadway's Dear Evan Hansen from Platt; Galvin was the first replacement. Since then, Platt reprised his performance in the movie adaptation of the Pasek and Paul musical and has gone on to appear in The Politician and The People We Hate at the Wedding, along with a stage return in New York City Center's gala production of Jason Robert Brown's Parade.
Galvin starred in The Real O'Neals before appearing in Booksmart, The Other Two, and The Good Doctor. On stage, Galvin followed up his run in Dear Evan Hansen by playing Ogie in Waitress on Broadway. Both Platt and Galvin are starring in the upcoming film Theatre Camp, co-written by Galvin and Platt with Molly Gordon and Nick Lieberman.
