Starting on Channel 4 tonight, American comedy drama This Is Us could be the next big US import. The series follows a group of people who were all born on the same day. Two of these are Kate and Kevin Pearson (Chrissy Metz and Justin Hartley), two of three triplets. However, their biological third brother was stillborn, so their parents Jack and Rebecca (Milo Ventimiglia and Mandy Moore) decided to adopt a son who was born on the same day named Randall (Sterling K. Brown) and was abandoned by his biological father. The series takes place in both the past and present as it looks at the life of the characters in their childhood and growing up. In the pilot episode, Jack wants Rebecca to uphold a family tradition, Randall is given a party by his friends at work, and Kevin has a crisis. This Is Us is on Channel 4 at 21.00.
