Jada Pinkett Smith plays one evil and dangerous villain on Gotham . But did her onscreen alter ego bleed into her life offscreen, causing her to injure her onscreen enemy Ben McKenzie on set? On Friday (McKenzie’s birthday!), the Gotham star revealed that he got hurt on set , posting an Instagram of a bloody gash on his head. E!News caught up with McKenzie at the Fox drama’s premiere party on Monday night and ask: did Smith cause his injury? “No!” McKenzie, who was still sporting a pretty serious cut on his forehead, told E!News with a laugh. “Although, yeah, that could happen too.”
