The kids of Netflix's "Stranger Things" weren't the only ones who experienced major physical transformations on the hit Netflix series.
Millie Bobby Brown, Finn Wolfhard and the other teenage protagonists went through puberty in front of audiences' eyes, but David Harbour turned heads when he appeared significantly slimmer in Season 4.
On Thursday, Harbour, who portrays the beloved Hawkins sheriff Jim Hopper, revealed that he lost about 80 pounds — down from 270 pounds to 190 — to attain Hopper's latest physique.
