There are few things more endearing than a man happy in his work.

And Michael Fassbender looked like a particularly mirthful murderer as he enjoyed the atmosphere on the set of Assassin's Creed in Spain on Monday.

The Irish hunk was guffawing with glee as he chatted with the crew between takes as they shot scenes on location in Almeria.

The mirthful murderer: Michael Fassbender was in a sparkling mood on the set of Assassin's Creed in Spain on Monday

The 38-year-old looked quite the beefcake in his medieval period dress, and seemed like he was having a great time as he made his money-spinning appearance in the film based on the popular video game franchise.

Michael was dressed in leather amour due to the fact he is playing a hunky Spanish assassin from the 15th Century named Aguilar in the time-bending feature.

The X-Men beefcake is also playing a man of modern times named Callum Lynch, who discoverers he is a descendant of the noted hitman.

Nobody likes a boaster Michael: No doubt the actor was telling his friends all about his Los Angeles Film Critics Association best actor win

You didn't get those in medieval Europe: The actor will surely have got rid of his bottled water when the cameras started rolling

Who's that boy: Michael was a man transformed when he pulled his hood over his head and took on the persona of Spanish assassin Aguilar

He's behind you: Hopefully Aguilar will not get caught out by such a simple ruse in the movie

For some hopefully important reason he has to relive his ancestor's memories to gain the knowledge and skills necessary to confront the holy order of the Templars, who are age-old enemies of the assassins, in the present day

Michael had plenty of reasons to be smiling on set after scooping the prestigious best actor gong when the Los Angeles Film Critics Association picked the best performances of 2015.

The group of professional critics cast their votes over several hours during an annual luncheon on Sunday.

The jolly actor won for his portrayal of Apple co-founder Steve Jobs in Danny Boyle's movie.

No doubt the 12 Years a Slave star will be hoping he can go one better than the best supporting actor Oscar nod he got for his turn in the 2013 picture.

Also spotted on set was Storm star Brendan Gleeson, who plays Callum Lynch's father, and who must also have a crucial role in the past also.

Taking the Michael: The actor is not doubt thrilled that filming took him all the way to Almeria

It's a knockout: No doubt Assassin's Creed will be better than the boxing movie it partly shares a name with

History lesson: The city of Almeria was founded by Calipha Abd-ar-Rahman III of Córdoba in 955 AD
