Filming on the final season of 'Better Call Saul' only wrapped a matter of weeks ago, and for the main star of the series it was his most memorable one yet.

Last July, Bob Odenkirk suffered a heart attack while filming his final season as lawyer (read: con artist) Saul Goodman in Netflix's 'Better Call Saul'.

The 59-year-old's sudden hospitalisation resulted in a huge outpouring of concern from his former colleagues, friends and of course fans of both 'Breaking Bad' and 'Better Call Saul'. Luckily, he was able to recover and resumed filming on the final season of his Netflix show six weeks later.

Appearing on 'The Late Show With Stephen Colbert' this week to promote his new memoir, Odenkirk recounted the ordeal that occurred during the summer.

He said he was "very lucky" that he was on the film set in New Mexico at the time of his collapse, and he thanked the various medical professionals who came to his aid straight away. He named Rosa Estrada, the health officer on the film set at the time who started CPR on him "and did it right", and also named Angie Myer who aided her.

Odenkirk admits to Colbert that he doesn't remember the day the heart attack happened, nor does he remember the following week while in hospital.

Moving onto the topic of filming the sixth and final season of 'Better Call Saul', Odenkirk said he wrapped filming his final scene on the set two and a half weeks ago. The actor has been playing the back-alley lawyer for over 10 years, first appearing in 'Breaking Bad' season two.

Putting Bob Odenkirk's sudden heart attack and his role in 'Better Call Saul' aside, Colbert then delved further into the star's recent memoir. Entitled 'Comedy Comedy Comedy Drama', Odenkirk admits writing the book was "so hard" because he "couldn't focus".

Hiding out in a cabin in a remote forest, as any writer might say is worth doing when writer's block occurs, the actor also brought along his own hilarious self-made dramatisation of his writing process, cementing his comedic roots. Take a look.

'Better Call Saul' season six hits Netflix later this year. The final season will consist of 13 episodes.
