Actor Bob Odenkirk was rushed to hospital after collapsing on the set of popular television drama "Better Call Saul" in New Mexico, US media reported.

Odenkirk, 58, was filming the final season of the show in which he plays luckless protagonist Jimmy McGill, a small-time lawyer and conman who transitions to an eventually prominent defense attorney under the name Saul Goodman.

The show is a spin-off of critically acclaimed "Breaking Bad", widely regarded as one of the greatest television series ever made.

In that show, Odenkirk plays the lawyer for schoolteacher-turned-drug dealer Walter White.

Entertainment publication TMZ said Odenkirk "went down" on set Tuesday and was "immediately surrounded by crew members who called an ambulance".

Odenkirk has received four Emmy and Golden Globe nominations for best actor for "Better Caul Saul" and has previously won two Emmys for writing on other productions.

"Better Call Saul's" sixth season is expected to premiere early next year.
