That Sarah Michelle Gellar cameo in I Know What You Did Last Summer totally caught me off guard! I seriously believed all the rumors that she wasn’t coming back, so seeing her as Helen Shivers was epic. The fact that Madelyn Cline was the only one to film with her makes it even more iconic. Now fans are debating if this dream sequence means Helen could somehow return for real. What do you think? #Entertainment #Movies #IKnowWhatYouDidLastSummer
