One of the most impressive roles an actor can nab in Hollywood is a double bill with themselves. It’s not easily done, but when actors such as Jake Gyllenhaal, Paul Rudd and Michael Keaton have pulled it off, it’s the ultimate test of technical filmmaking and acting ability. In HBO Max’s first original film, An American Pickle, Seth Rogen plays a Jewish immigrant factory worker who is preserved in pickle brine for 100 years and lives to meet one of his descendants living in the present day, also played by Rogen.
