No, but his wife is.
Jake Gyllenhaal is not a Muslim Him acting in a video game based movie Prince of Persia does not refer to him as a Muslim. And the Movie Prince of Persia does not hint that Persia is a all Muslim country some of them are not Muslims (Persia in the modern world is actually Iran)
The implication behind this question is that there is something wrong with Shiites or that Shiites should be "fixed". This is a very flawed perspective. You should reach out to your Shiite Muslim brothers and sisters rather than worry about what you do not know.

No Muslim has the right to say wrong about Sunnis or about Shiites. All Sunnis and Shiites are Muslims. The non Muslims are only those who denies that no God except one and only one God and also denies that Muhammad (PBUH) is God's prophet. It is not of interest of any Muslim to know why someone whoever doesn't like Shiites or doesn't like Sunnis. No Muslim, whoever, has the right to expel another Muslim from Islam because he some views different from his/her. Any Muslim believing that No God except one and only one and that Muhammad (PBUH) is His prophet and messenger, then he/she is Muslim and only Allah (or God in English) would judge him on the Day of Judgment. Both Shiites and Sunnis are Muslims. Refer to related question below.
