Actor Louis Mandylor has been hospitalised for heat exhaustion after collapsing on the set of his new movie in Texas.

The My Big Fat Greek Wedding star, 47, was shooting scenes for Daylight's End in the city of Tyler on Tuesday (22Jul14), when he lost consciousness as temperatures soared past 90 degrees Fahrenheit (32 degrees Celsius).

He was taken to a local hospital, where doctors also treated the actor for dehydration, which left him close to suffering kidney failure, according to Tmz.com.

He is expected to make a full recovery and is due to be discharged on Friday (25Jul14).
