The film revolves around ruthless corporate headhunter Dane Jensen (Gerard Butler), who works at Blackridge Recruiting arranging jobs for engineers.
"Performing a scene with @MaxwellJenkins8 was a challenge. He is such a fine actor. #TheHeadHuntersCalling #Toronto," Kher wrote on Twitter.
The "Baby" actor also shared a picture of him with Maxwell posing beside their respective chair on the sets.
"The Headhunter's Calling" is written by Bill Dubuque, who has earlier penned the Oscar-nominated movie, "The Judge" and "The Accountant".
