Bill Skarsgård underwent a strict diet and intensive workout regimen to prepare for his role as Eric Draven in the reboot of 'The Crow'. Director Rupert Sanders revealed that Skarsgård maintained a diet primarily consisting of steak tartare and raw eggs, which he continued from his previous film, 'Boy Kills World'. Skarsgård focused on weight training, gradually increasing weights while ensuring he didn't become overly muscular, as the character Eric shouldn't appear too ripped before his transformation into the Crow. The actor's dedication to fitness left his co-stars in awe, especially as they indulged in less healthy meals on set. Skarsgård's commitment is evident in an intense scene where his character infiltrates an opera house, showcasing his physical transformation. Despite the arduous preparation, the film has faced criticism at the box office, with early projections suggesting it may not perform well.
