The Hulk, one of the big summer movie blockbusters, premièred in London on Thursday.
Connelly signed fans' autographs
More than 1,000 fans lined London's Leicester Square to greet the film's stars, which included eight-months pregnant Jennifer Connelly.
Eric Bana, who plays Hulk's human altar ego Bruce Banner, and the movie's acclaimed Taiwanese director Ang Lee also made an appearance outside the Empire cinema.
Bana, the Australian actor who had flown in from Malta from the set of Troy, joked he was not wearing the right coloured clothes.
Arriving in a charcoal grey suit, he said: "I looked everywhere for a green suit but I couldn't find a nice one so I've had to make do with this."
Other celebrities at the première included Australian pop star Holly Valance, boxer Chris Eubank and model Nell McAndrew.
A giant mock-up of the green monster loomed above the crowd on the facade of the cinema.

Fans from Europe and the US joined the crowds, while one man dressed in a ripped shirt and green make-up in an attempt to get a ticket for the screening.
Peter Happlewhite was offering £100 for a ticket, and said he had had a couple of offers, but "everyone has been with a spouse, and their spouses haven't wanted to go in with me".
Other fans arrived at the première on the spur of the moment.
Students Hannah Brooks, 16, and Jenna Miles, 18, from Essex, brought a camera and managed to get shots of Valance, Connelly, Bana and McAndrew - despite only coming in to London for a day's shopping.
The £100m action film, starring Bana and Connelly, has broken June box office records in the US, taking $62.6m (£37.6m) in its first weekend.
