Bob Odenkirk let his social media followers know he is back to work on Better Call Saul.

The actor, 58, shared an image from the makeup room as he prepared to shoot a scene for his hit TV series on Wednesday.

'Back to work on Better Call Saul!' his note began. 'So happy to be here and living this specific life surrounded by such good people. BTW this is makeup pro Cheri Montesanto making me not ugly for shooting!' 

It has been over a month since the actor suffered a 'small heart attack' on the New Mexico set that caused him to collapse.

The Emmy-winning actor is currently filming the sixth and final season of his Breaking Bad spin-off, which began production on March 10 this year. 

The series centers around lawyer Jimmy McGill [Odenkirk] who, over the course of several years, mishaps and questionable ethical choices rebrands himself as smarmy criminal attorney Saul Goodman in Breaking Bad.

A prequel spin-off of the Bryan Cranston series, Better Call Saul managed to carve out a home for itself among televisions great dramas. 

Executive producer of Better Call Saul, Peter Gould, previously confirmed the show's final season will consist of 13 episodes rather than the usual 10.  

'From the beginning when we started this, I think all our hopes and dreams were to be able to tell the whole story,' Gould said in a statement.

He added: 'And make it to be a complete story from beginning to end. We're going to try like hell to stick the landing of these 63 episodes.'

The final season is scheduled to air in early 2022.  

In August Bob gave fans an update on his health after his late July heart attack on set in New Mexico.

'I am doing great. I've had my very own "It's a wonderful life" week of people insisting I make the world slightly better, began the actor in a tweet.

Odenkirk ended his brief update by sending fans his 'love' and thanking them for their well wishes.
