Oleg was a bit of a hard case for us. We had filmed this casting and were happy enough to invite him back for a few scenes, but sadly Oleg turned us down.
We noticed a while later that he had then gone and filmed for another studio a while later, so we called him up for a chat.
In the end it turned out that he only wanted to film 1 scene, and since we put quite some time into training with a boy before they film, doing this for just 1 scene wasn't worth it.
We'll have to see what the future hold.
