Mega-star team-ups are all the rage these days. We’ve got everyone who ever kicked ass in the 1990s joining forces in The Expendables 2, Arnold and Stallone raiding The Tomb shoulder to shoulder and…um…Oh God, what am I forgetting? Anyway, Warner Brothers has its sights set on creating another, reportedly hoping to convince Tom Cruise (Rock of Ages) and Robert Downey Jr. (The Avengers….Right, of course!) to sign on for action- comedy El Presidente, which Jay Roach (Meet the Parents, HBO’s Game Change) is currently in talks to direct.The flick would see Cruise stepping into the role of a gung-ho Secret Service agent assigned to protect a particularly reviled former President of the United States played by Downey Jr. At the moment, offers have not been made to either actor, but that could be forthcoming. Hit the jump for more.The script for El Presidente comes from Parks and Recreation scribe Dan Goor. Per Vulture, WB execs have been particularly high on Cruise for this part after watching what he did with the role of super-rocker Stacee Jaxx in this summer’s forthcoming Rock of Ages.I have to say, while it’s still little more than a pipe dream right now, I hope this comes together. Cruise has proven his comedic chops more than once. But even if he were to play the role totally straight, I get the sense that his Ethan Hunt shtick play well off Downey Jr. in “bumbling sleaze” mode.In addition to Rock of Ages, Cruise’s upcoming schedule includes the already-wrapped crime drama One Shot, currently-filming sci-fi actioner Oblivion and further-off stuff like All You Need is Kill and the Van Helsing reboot. Downey, meanwhile, is gearing up to shoot Iron Man 3 with new director Shane Black.
