His name is pronounced "Yih-rzhee Wey-dyeh-leck".

[on directing Jirí Machácek and Bolek Polívka] When they started improvising, I just waited until they were done and then we shot it according to the script. The interesting thing is that while I knew both of them from previous films, I realized only now that although they are perceived as typical creative actors with an inclination to improvise, both have different ways how to go about it. While Jirí likes to rehearse a lot and then can repeat the act, which looks like improvisation, many times over, Bolek acts the same part differently each time. So when I wanted a certain result I had to 'tire Bolek out' by letting him work with Jirka to get exactly the shot I wrote in the script.
