I don't quite understand this part
"Poitras, who profiled another celebrated data warrior, Edward Snowden, in Citizenfour, filmed with Assange from 2010-2012"
The commas are confusing. I know that "Edward" links to the celebrated data warrior but I am confused with which part "in Citizenfour" links to and the part after it. Please give a thorough explanation of the entire sentence which tells the connections between different parts. Thanks a lot.
