In the hilariously strange 32-second clip uploaded to Hopkins' official Twitter account, the 80-year-old is seen flailing around wildly and making goofy faces directly into his phone's camera while a frenetic song plays loudly in the background. It's part playfully deranged, part hilarious, and 100% weird. It's even more unsettling coming from the man whose most memorable film role was that of a legendarily creepy serial killer.
Since the Tweet was posted on Sunday, it's gone viral and racked up nearly 60,000 retweets and 180,000 likes as of this writing. Reactions, as you might imagine, have been all over the place -- ranging from from concern to praise.
