Counterpart (Seasons 1–2)

Counterpart (2017) is a Starz spy drama you can watch online on iFILM, built around a quiet Berlin UN bureaucrat who discovers his agency is sitting on a passage to a parallel world. J.K. Simmons plays Howard Silk — and his dimensional counterpart — in what is genuinely one of the most physically and emotionally distinct dual performances in recent television.

The two Howards have lived opposite lives. One survived in obscurity; the other hardened into a cold-eyed intelligence operative. When they're forced to swap sides, the show stops being a sci-fi premise and starts being a character study about how circumstance shapes identity. Olivia Williams, Nazanin Boniadi, and Richard Schiff round out an ensemble that keeps the stakes grounded even as the mythology grows.

Two full seasons aired before Starz cancelled it in 2019. Both seasons are here and tell a complete story. Stream all episodes of Counterpart on iFILM.
