Everything is backwards in the world of Dr Buryznski.
This film is available free and in full online with full permission of its makers, no concerns about movie piracy there. However, while film makers generally ensure they get payment for their work, it becomes understandable when viewing this: it is nothing more than a one-sided advert for the Burznski "clinic" (in reality a second floor room in a multi-occupied office block).
The financial disregard stops there however. And boy, does it stop. Normally clinical trials, which is how Burnyski recruits his patients given his claimed therapy is not licenced and has no proper data published on it, are fully paid for by the people running the trial. While some patients can get access to new drugs and other supportive care free via taking part in trials, Buryznski's patients have to pay £200,000 or something similar. Interestingly, Burzynski's published and publically available financial returns account for his trial spending in a totally different way to normal trials and allow the impression they may not be investments for future product income. This is highly unusual given the staggering claims made for the therapy in this "documentary".
Much material is online now about Burzynski's publications, scientific qualifications, claimed results, financial charges etc as the result of attacks on bloggers critical of his activities, and the "Streisand effect" that followed. The worst of these attacks, possibly, was directed against Rhys Morgan, a 17 year old blogger who magnificantly turned the tables on the attempted silencing. Take the time to read what's out there, then compare to the calims made in this "documentary" and guage its value.
Burzynski is unique in current medical science in charging for clinical trials instead of paying for them: there is no better example of "caveat emptor".
