Saldana's castmates even came to her aid during a group photograph prior to the screening, when she was in danger of stepping on her gown.
Eve donned a strapless sued dress for the red carpet walk, and Captain Kirk actor Pine was attired in a stylish grey suit.
Simon Pegg also smiled gleefully for the press as he entered tonight's premiere, with Karl Urban and Star Trek into Darkness co-writer Damon Lindelof also making appearances.
Cast members Pine, Quinto, Urban, Saldana, Eve, Pegg and Benedict Cumberbatch previously posed with Abrams in front of Tower Bridge ahead of the film's City Hall press conference earlier this morning.
A sequel to Abrams's 2009 reboot, Star Trek Into Darkness sees the crew of the Enterprise face a one man weapon of mass destruction in the form of Cumberbatch's rogue Starfleet officer John Harrison.
Star Trek Into Darkness opens in the UK on May 9 and May 17 in the US.
I know you'll love this, ONTD.
Nooooooooooooo, he's looking old and less Clooney and more Hemingway. Remember when you tried this a few years ago, bb? Disaster.
ONTD's favorite men no. 1 and 2
Kind of a boring premiere, tbh. Also missing John Cho and Anton Yelchin. And Bruce Greenwood.
