The first look at Sam Worthington, who returns as Perseus in Wrath of the Titans, isn’t really the story here. What is more interesting is the plot synopsis as provided by Entertainment Weekly who writes about the story for the Clash of the Titans sequel with apparently spoilerish comments from director Jonathan Liebesman:
In the Greek-gods-run-amok sequel Wrath of the Titans (out March 30), Perseus (Sam Worthington) must journey into the underworld after his dad, Zeus (Liam Neeson), 
is kidnapped by Hades (Ralph Fiennes). The trident is but one of several celestial weapons Perseus has to bring together “in order 
to create an über-weapon,” says director Jonathan Liebesman (Battle: Los Angeles). “But that’s probably a massive spoiler. I 
haven’t practiced being spoiler-
proof yet.”
So Zeus is kidnapped? That happens? Is this the “weight” Worthington was talking about when he said the following to Buzzine:
You make Clash 2 weighty. Clash 1 is a video game. You make Clash 2 weighty. You take everything you’ve learned and go, “I’m not doing this f*cking shit! I’m going to do a weighty script in a blockbuster.” That’s the bigness of a blockbuster. They’re very hard because they’re done by such a machine, so you try to get that weight that an independent can allow you — that freedom that they have on an independent script — and then you try to fit it into a blockbuster where there’s a whole set of people who have a say. With something like Clash 2, that’s definitely what we’ve aimed for.
I guess we’ll find out soon enough.
As it says, Wrath of the Titans is set to hit theaters on March 30, 2012 and it will again be converted into 3D. Along with everyone mentioned above, the cast also includes Edgar Ramirez as Ares, Toby Kebbell as Agenor, Rosamund Pike as Andromeda, Bill Nighy Hephaestus and Danny Huston as Poseidon.
