Risky Reels was a location in Fortnite: Battle Royale that is located in the top right corner of the map. It was added at the start of Season 4, removed in Season 7, got a miniature version in Season X, and returned in Chapter 2: Season 1 as an unnamed location.
Risky Reels featured a small crater (similar to the one at Dusty Divot, but not as large) in the center of the area surrounded by trucks. It has since been filled up. It had a similar 'Movie' theme to Moisty Mire and offers small huts and houses on the outskirts of the area. It is most noteable for the giant cinema screen located at the front of the location, as this was where the cinematic 'Season 4 Trailer' was filmed.
Additionally, in the game files, you can find a short video of Ralph from "Wreck-It Ralph" walking into the frame from the side, waving at the camera, and then walking off. This "film" can be seen displayed at Risky Reels on the movie screen. Showing time of the movie is random, and does not even display in some matches.
As of update 7.0.0, Risky Reels is gone. It is now The Block.
