“Game of Thrones” comes to the (hopefully) climactic end of its eighth and final season on Sunday. But some actors in HBO’s hit sword-and-sorcery epic have already made their exits. The show has been notorious for killing off main characters and fan favorites.

Beverage carbonation brand SodaStream is tapping into the excitement for the finale by giving three actors a chance to say “goodbye” to plastic water bottles, the same way their characters have had to say goodbye to the show—and their lives.

Icelandic strongman Hafthor Julius Bjornsson, who played “The Mountain,” joins Kristian Nairn, who played the simple-minded Hodor and Hannah Waddingham, who played Septa Unella, in a 60-second spot full of slow-motion struggle and faces wracked with tragedy, all brought on by plastic bottles. They’re expensive, heavy and don’t biodegrade. In this spot, they also leap out of cabinets to attack people and fall at the most inopportune times.

All three actors have appeared in previous SodaStream campaigns, most notably a lengthy, on-set spot featuring Waddingham, who reprised her bell-ringing from season 5, and Bjornsson, who broke the fourth wall to pitch for the product. This time around, The Mountain’s “mother” helps make the sale and slips in a few medieval jokes to boot.
