Prime Video has released the first trailer for Season 4 of "Reacher," officially confirming Alan Ritchson's return as the hard-hitting former US Army military police major, ahead of the season's premiere on 12 August. The trailer debuted during a San Diego Comic-Con panel that also promoted the show's upcoming spin-off, "Neagley," starring Maria Sten, marking a significant step in expanding the franchise's universe following the acclaimed third season.

The panel, held on 25 July at San Diego Comic-Con, saw Ritchson, Sten and other cast members discuss the new season, in which Reacher is once again drawn into danger after trying to do the right thing. The "Neagley" spin-off follows on 16 September, just over a month after Season 4 launches. Reacher has already been renewed for a fifth season, with Ritchson confirming filming is underway even before Season 4 has aired, and with 30 novels still to adapt, the show's future looks secure, with Season 5 expected sometime before the end of 2027.
