"Leonardo DiCaprio’s ‘CEO type’ character is a guy who can dive into people’s dreams to implant or extract information. The tool used isn’t a big machine, but something that can be injected, and is therefore portable. Ellen Page, Tom Hardy and Joseph Gordon Levitt play members of DiCaprio’s team. She’s a ‘dream architect’. The roles of the two guys are less certain, but the fact that Joseph Gordon-Levitt is fighting two guys in the trailer is interesting, if they are in fact working together."
