New to Stream

The Eternals, Disney+

Here's the latest Marvel movie to make the streaming move to Disney.

Our own Barry Keoghan is in the cast of this Marvel movie that includes Gemma Chan, Angelina Jolie, Salma Hayek, Brian Tyree Henry, Don Lee, Kumail Nanjiani, Richard Madden, and Kit Harington.

The story begins millions of years ago when the cosmic beings known as the Celestials genetically experiment on humans, creating the super-powered and near-immortal beings and a more monstrous off-shoot known as the Deviants.

The two races move behind the scenes throughout human history while also engaging in cosmic powerplays.

Among the Eternals are Ikaris, fueled by cosmic energy; Sersi, who relishes moving amongst humans; and Thena, often mistaken for the Greek goddess Athena.
