Del Toro went on to discuss how his character’s motivation may be withheld at times:
“For example, they told you ‘Now you have to go in this restaurant and kill this person.’ And then you ask: ‘Who? The blue haired girl, or the guy with the wig?’ And you don’t get the answer. And suddenly, you heard ‘Action!’ And you have to go along: so you shoot everywhere and they’ll find a solution for the final cut.”
Del Toro’s remarks offer interesting details on this specific scene, but also alludes to the nasty nature of his character. In the comics, The Collector is an immortal who, after living peacefully for a thousand years with a wife and daughter, ends up losing them both. He is the last surviving member of his species, playing an important role in the Marvel Universe, and ties directly to Thanos, the big bad guy whose presence was teased during the mid-credits scene in The Avengers.
The Collector also has a limited clairvoyant ability, and foretold the threat Thanos poses to the galaxy. We’ve covered what The Collector’s presence could mean in detail here (which includes insights into the film’s possible connection to the The Avengers), and it’s still unknown just how much of the character’s comic book mythology will be included. This insight into at least this one scene hints at The Collector’s capacity for violence, and while we still think that the main villain of Guardians will be a henchman of Thanos, Del Toro’s The Collector definitely sounds like a threat who won’t be ignored.
