Fans and critics alike were very thrilled with the third season of "The Boys" a few months ago. With Jensen Ackles and his role as Soldier Boy, a "Supernatural" star was already added to the cast. And now, the next actor from the series, which ended in 2020, has already been confirmed for the upcoming fourth season. As told by The Hollywood Reporter, Jeffrey Dean Morgan is set to join the cast in the near future. The 56-year-old played the role of John Winchester in "Supernatural" and can also be seen starring as Negan in "The Walking Dead". In fact, these are not the only two former "Supernatural" actors, since Jim Beaver, who embodies Robert Singer in "The Boys", was also previously featured there. For this very reason, many fans are amused by the casting and already suspect a crossover between the two series. After all, showrunner Eric Kripke is also the creator of "Supernatural" and seems to have been deeply impressed by some people. Sadly, it is not apparent yet which character Jeffrey Dean Morgan is going to play, though many are banking on Tek Knight. Like Ironman, Tek Knight wears a high-tech suit and is regarded as a wacky, sex-addicted parody of the Marvel superhero. You could definitely imagine Morgan in the role, however, nothing has been officially confirmed yet. The same goes for the release date of "The Boys" Season 4, but we will keep you up to date as usual.
