Sabrina Carpenter made a surprise cameo during Saturday Night Live on Jan. 17, joining musical guest A$AP Rocky and host Finn Wolfhard in a hilarious sketch.

Finn Wolfhard's 'SNL' appearance featured a little help from his "Stranger Things" friends Gaten Matarazzo & Caleb McLaughlin.

“Stranger Things” star Finn Wolfhard and comedian Ben Marshall poked fun at both “Harry Potter” and “Heated Rivalry” during a racy pre-taped “Saturday Night Live” sketch this weekend. The bit, titled “Heated Wizardry,” spoofed HBO’s upcoming “Harry Potter” TV series before taking a sudden and heated turn.

Finn Wolfhard and Ben Marshall portrayed franchise characters Harry Potter and Ron Weasley who are opposing quidditch players, instead of hockey players like the HBO series.

For being only 23 years old, Finn Wolfhard has quite the varied resumé.
