Could Keanu Reeves make a cameo appearance in the hit series "Yellowstone"? While promoting the release of "John Wick: Chapter 4," Reeves was asked during an interview whether he would up for taking on a "surprise role" in the hit series. "I’d love to do a western so yeah, yeah sure," he replied to ET Canada. The hit western drama – which is set to return for the second-half of season five this summer – has been dominating headlines after rumors circulated "Yellowstone" would be ending after the current season due to drama surrounding the lead role of John Dutton, who is portrayed by Kevin Costner. Reports recently surfaced that the actor was not willing to work as much to film season five and season six.
