Without David Duchovny and Gillian Anderson clicking onscreen as the lead agents, The X-Files almost certainly wouldn’t have lasted for nine seasons, two movies, and one revival.
According to Gillian Anderson, clicking with David Duchovny is what actually won her the role of Scully.
Fans were also lucky to see Gillian Anderson reprise the role of Scully in a 2016 TV revival.
It’s no real surprise that David Duchovny was cast before Gillian Anderson.
