The actor, who reprises the role of Jesse Pinkman in Netflix film El Camino , told The Independent that, despite fierce competition, the scene in which he discovers the body of his girlfriend Jane (Krysten Ritter) was one of the hardest days of his professional career.

He revealed that a special rig was made for Ritter so that Paul didn’t hurt her as his character attempts to resuscitate her and that he struggled to pull himself back emotionally after one take got particularly tough.

“I don’t know if you know this, but they made a special rig for Krysten to wear so I could really just hit her as hard as I could without it hurting her. That was pretty brutal. I went to a place that day. It was hard for her as well. I remember one take, when they yelled 'Cut', I just – I was so devastated that I just couldn’t come back from it. As was Krysten – she started crying and I thought I’d hurt her from the thing that was wrapped around her. It was just so hard on her emotionally.”
