Darth Vader battles Gandalf in new series from Heroes star Milo Ventimiglia

Heroes star Milo Ventimiglia is set to appear in and co-produce Ultradome, a new scripted Web series in which warriors from sci-fi's most popular franchises settle hypothetical disputes in a special-effects showdown.

"My whole life has been spent engaged with friends in intellectual debate ... like whether Captain Kirk is tougher than Spock or if Middle-earth is a more difficult place to live than Tatooine," Ventimiglia said in an interview with The Hollywood Reporter. "With Ultradome, we can bring these debates to the public and settle them in the most logical way possible: through armed combat."

In each three- to five-minute episode, two characters engage in a heated debate—"Who's tougher, Harrison Ford as Han Solo, or Harrison Ford as Indiana Jones?"—then are transported to a stadium where the duo engage in single combat using all the weaponry, skills and pop-culture touchstones from their respective heroes' creative arsenals.

The concept is similar to Spike TV's new series Deadliest Warrior, which reconstructs hypothetical matchups between, for instance, a samurai and a Viking. Only Ultradome is played for laughs with pop-culture-driven battles and shows fans fighting instead of trying to re-create the iconic warriors themselves.
