After his heartbreaking portrayal of Luke Crain in The Haunting of Hill House, Oliver signed onto the series's next season without really knowing what his role would be. It turns out, he was originally intended to play the gardener, AKA the love interest of Dani (played by Victoria Pedretti).
"It was an iteration where Victoria and I were going to play lovers," he told Entertainment Weekly, recalling the initial role. "And then I think Netflix was like, 'No, that's a bit weird seeing as [you played] twins.'"
