Principal photography took place over 17 days between December 2020 and February 2021.
Originally conceived as a web series, executive producer Scott Day decided in post-production to edit Wanda & Sully as a feature film after test screenings.
Executive Producer Scott Day funded a majority of the film's budget on his own by working at a meat factory in Geelong. The rest was gathered through crowdfunding and film grants.
Scott Day and Joshua Marchant have said that their influences behind the screenplay are Election (1999), The Social Network (2010), Citizen Kane (1941), Network (1976) , Die Unbestechlichen (1976), 21 Jump Street (2012), and Community (2009).
The role of Mr. Redwood was written for Dave Callan, but the COVID-19 pandemic prevented him from entering Melbourne for filming. The role went to Mitchell James O'Neil.
