A fourth season of Lucha Underground is in the works, according to PWInsider. Production is hoped to begin either in the late fall or early winter as soon a schedule is worked out. A source noted that it could film in November although nothing is confirmed.
A third season has already been filmed and completed, which debuts later this year on The El Rey Network. At this stage the show will have clocked up to 100 episodes, which is the amount that syndicators look for when trying to license shows internationally.
