Of all the summer's potential blockbusters, "The Bourne Legacy," the Matt Damon-less continuation of the spy series, has the most to prove. Series tend not to fare well once the star exits, but the latest trailer for "The Bourne Legacy" is making us believe that it could buck the trend.

Here are our five key scenes from the new "Bourne Legacy" trailer.

Weisz's Role Revealed
Until now, most of the promo material has focused squarely on Jeremy Renner's Aaron Cross and how there was "never just one." One of the first things this full trailer does is formally introduce us to Marta, the doctor Rachel Weisz plays in the film. (Her hand appeared briefly in the first trailer.) When Edward Norton's Agent Byer decided to liquidate the operation, both Marta and Cross find themselves in harm's way. That's the set-up that eventually brings them together to go on the run.

Connections to the Past
Perhaps the most intriguing element of the new trailer — besides how badass Renner is — has to be the clear connections to the previous film, "The Bourne Ultimatum." Both Corey Johnson, who plays the government crony, and Paddy Considine, who didn't survive the events of "Ultimatum," show up in the trailer. It appears that the events of "Ultimatum" and Bourne's appearance in Manhattan spur the events of "Legacy."

Jason Bourne Again
Speaking of Jason Bourne, there's Matt Damon's face right there in the trailer. The actor has made it clear that he himself won't appear in the newest addition to the series he led through three films, but his headshot does briefly appear on a newscast in the trailer. Director Tony Gilroy told us during our Summer Movie Preview that Bourne's presence would be felt in the early parts of the "Legacy." "What happens in 'Ultimatum' is really the spark that's blowing open the door to this movie because the Jason Bourne story is exploding out into the public," he said. "Being impossible to conceal any further is causing problems for this much larger conspiracy. 'Ultimatum' plays in the background of the very beginning of this film."

Agent Aaron "Moto" Cross
As with the teaser trailer, a good portion of the full trailer focuses on the chromosomal enhancements that have been made to Aaron Cross. He heals quickly, and he can grind a railing with a freakin' motocross bike. Was one of the "inconsistencies" within Treadstone that the characters talk about in the trailer the inability to grind a railing with a freakin' motocross bike?

Matt Who?
If this trailer does one thing particularly well, it silences all of Renner's doubters. His action on display here is definitely on par with the kung-fu antics of Matt Damon. Whether he's on the bike or sliding between buildings or emerging from freezing water with a full beard, Renner looks poised to take the reins in style.
