'War of the Worlds' Season 3 is all set to debut in September and the latest season. Known for its dark and grim take on H G Wells' infamous alien invasion novel, the Howard Overman-created series will return with a more gripping tale in their new installment. Already making waves, the season will pick up from event two where quite a few questions were left unanswered.

In addition to the promising plot, the cast was pivotal to the show's success as it featured a blend of veterans and young names, all playing their parts. Gabriel Byrne, Daisy Edgar-Jones, and  Lea Drucker have been looked at as the more vital cogs of the sci-fi horror drama and ahead of the latest season, we look at who plays whom in the hit series.
