The recent casting of Josh Brolin as the voice of Thanos in Marvel's upcoming "Guardians of the Galaxy" isn't a huge surprise considering the giant purple Marvel supervillain character has long been rumored to play a role in the wacky outer space saga.
Whilst he won't fully shine until the third "The Avengers" in 2018, his presence will be felt in 'Guardians'. Vulture claims to have details on that presence, saying it will be more than just another post-credits appearance.
POTENTIAL "GUARDIANS OF THE GALAXY" SPOILERS AHEAD
According to them, the character first appears and will spend most of his brief appearance communicating via a hologram. He will be a behind-the-scenes figure throughout, essentially pulling the strings of the two villains of 'Guardians' - Ronan the Accuser (Lee Pace) and Nebula (Karen Gillan).
The character will apparently share a scene in the flesh with those two as well, will be referenced often and fearfully by others, and apparently will sport familial ties with Gamora (Zoe Saldana).
The site also claims that one of the Infinity Stones, referred to by Benicio del Toro's The Collector character in the film as the Power Stone, will play a part in the plot.
