Undisputed 2: Last Man Standing

Michael Jai White ("Iceman" Chambers) stated that despite being on screen rivals, he and Scott Adkins (Boyka) got along very well off camera because neither of them were method actors. "On camera, we'd have on our mean faces and be trying to intimidate one another. But as soon as the director yelled 'Cut!', we were back to talking about places to eat good salads."

Stevie is seen injecting drugs after George and Yuri's training sequence. Letting alone the fact that his arm has unbelievably good veins for someone who has been shooting for years, and the fact he appears to inject retrogradely into muscle rather than vein there is in addition a revealing prop: he pushes the needle about 3cm into his arm and then pulls it away revealing that the needle is now 3cm shorter. In a prop like this the needle pushes into the syringe giving the illusion that it goes into the body. Normally the needle is spring-loaded so that it pushes back out, but this did not occur with this prop.
