And in one of these surreal scenes, he comes across Tilda Del Toro’s Mona Lisa, who represented the other side of the gangster’s life apart from his family.
Embodying one of Capone’s ex-lovers, she is the mother of his rumoured illegitimate child who ends up violently confronting him.
Speaking exclusively with Express.co.uk, the Chicago-born Tilda shared details of rehearsing her “very aggressive” scene full of pushing, pulling and slapping, which actually ended up with everyone in fits of laughter.

Tilda recounted: “I came in and pulled Tom towards me and slapped him and then I pushed him on the couch.”
“The couch was a little lighter than in the scene because it was a production couch and it flew all the way back! We kept doing the scene and then Josh yelled ‘Cut!’”
There was silence on the set until the director said to her: “Tilda, I do NOT want to mess with you!”
The actress said, “He was okay with it! After that, he would say, ‘It’s okay, you can slap me.’”
For Tilda, it just showed how committed Hardy was to the Capone role, as she highlighted how uncomfortable his prosthetics were and especially his bloodshot contact lenses.
She said: “People don’t realise how hard prosthetics are on actors and his eyes were hurting him a lot because he had these contacts on. So I definitely felt bad for him.”
The Mona Lisa actress shared how Hardy would ask if she needed anything from him and would always treat her with respect as an equal actor.
She added: “That was a great experience. He was extremely professional, respectful, very aware and fully present.
“Tom was giving as an actor and really engaged in the work. He was very kind to me. I felt like he was very confident and when he needed to deal with something specific he did.”
Capone is streaming on Netflix UK now.
