This is called "Gettin' Wet on Wet with Deadpool 2" and it's the slick new, and wonderfully bizarro, teaser trailer for Deadpool 2. It shows Deadpool actor Ryan Reynolds (we assume) dressed in the superhero's costume and then dressed like the late TV painter Bob Ross, giant white fro and all. You have to sit through a minute and a half of weird, and hilarious, banter and "painting" just to see flashes of the film.
Even the description is off the wall:
After surviving a near fatal bovine attack, a disfigured cafeteria chef (Wade Wilson) struggles to fulfill his dream of becoming Mayberry's hottest bartender while also learning to cope with his lost sense of taste. Searching to regain his spice for life, as well as a flux capacitor, Wade must battle ninjas, the yakuza, and a pack of sexually aggressive canines, as he journeys around the world to discover the importance of family, friendship, and flavor – finding a new taste for adventure and earning the coveted coffee mug title of World's Best Lover.
Deadpool 2 hits theaters June 1, 2018.
Here's a closer look at that Norman Rockwell-esque painting at the end of the trailer:
