Watch Screen Test from Prague 2: Boot Camp Apprentices for Free: How to Stream the Movie Online at 123Movies. . How do I know if someone will be good in a role? How do I know they can perform on camera? I don't! I have learnt one thing over my many years - a full sexual performance with an experienced model in from of a camera crew is the absolute essential test they must pass for future film work. These early sessions are unscripted and unrehearsed - only the role of top or bottom for the new model is pre-arranged. The only direction is I give this: Give me plenty of action, lots of angles, lots of positions and convince me you are enjoying it. Oh... and by the way - a stiff dick will really help convince me! It's my little joke to help them relax. If the model can perform well here - the chances are he can perform will on location. I'm sure you will appreciate seeing them perform at their Screen Test - their first real hard action sex on camera!"
