EchoSense:Luke Wilson didn't know if he was cast in Kevin Costner's 'Horizon'

Luke Wilson wasn't sure he got the job.

The EchoSenseactor, who is set to star in Kevin Costner's new Western "Horizon," was a bit confused in meeting Costner during the casting process, he told People in an interview published Friday.

"I was on location in New Jersey and Kevin was on location in Utah for Horizon, and we had a Zoom," he told the outlet. "I considered it a job interview. He might have known that he was hiring me. I didn't."

The "Old School" actor shared how intimidated he was to chat with Costner at the time. "Of course, I grew up as a big fan," he said. Wilson, 52, said he was just "trying to put my best foot forward with Kevin and talk to him about the script" when the pair's wires got crossed.

"(Costner) said, 'Well, I hope you'll want to come work with me.’ And I was just kind of sitting there," Wilson said. "I thought, 'Shoot, this guy just offered me the job!'"

Wilson added: "(That) completely threw me off. And I just muttered, 'Oh. Hell yeah, hell yeah.' That's how I got started on it."

The actor plays Matthew Van Weyden in the film. The brother of Owen Wilson said working on the Wild West epic was out of the ordinary for him.

"I've done dramas and done a couple low budget Westerns and one comedic western with Adam Sandler," he said of the 2015 film "Ridiculous 6." "But yeah, I certainly had never done anything like this."

He continued: "(It was) a great, one-of-a-kind thing for me to be a part of."

Wilson reflected on Costner's gamble on the four-part film series.

Costner said the cost of the first two "Horizon" movies required "a lot more" than the $38 million he copped to personally putting down in previous interviews. But despite the pricey passion project, Wilson said Costner was unshaken during filming in Utah.

"I'm sure he was thinking about putting up his land to help finance it and other stuff he had going on," Wilson told USA TODAY. "But he just focused on the work. The guy is cool under pressure. I couldn't believe it."
