Legendary Pictures Chairman and CEO Thomas Tull made a $500,000 contribution to a pro-Hillary Clinton super PAC in August, joining a list of other high-dollar donors, including George Soros and Fred Eychaner.

The super PAC, Priorities USA Action, raised $23.4 million during the month, with $41.5 million on hand by the end of the reporting period.

Among the biggest donors were Soros, who gave $2.5 million to the super PAC, and Eychaner, the chairman of Newsweb Corp., who gave $3 million.

According to Federal Election Commission records, Tull gave $1 million to Priorities in December. Among the other major donors to the group are Haim Saban and his wife Cheryl, who have given a total of $10 million to the super PAC this cycle. Jeffrey Katzenberg and Steven Spielberg each gave $1 million.
