I mean, O’Donnell is an arguably important part of the DC film world. having starred as Dick “Robin” Grayson in Joel Schumacher’s Batman Forever and Batman & Robin, but that was back in the mid-1990s.
But he just…isn’t the same person as Stephen Amell.
Admittedly, O’Donnell has aged spectacularly well, and is probably capable of being an Arrow star at this point in his career.
Not only did that bartender momentarily get Stephen Amell mixed up with Chris O’Donnell right there at the bar, but that person has clearly never been aware of who actually plays the titular superhero on Arrow, apparently thinking that O’Donnell has been a mainstay on The CW for the past six years, working to spearhead the entire Arrow-verse.
