No red carpet for 'Batman v Superman' London premiere after Brussels attacks

(Recasts first paragraph with premiere under way, adds security tightened in Britain)

March 22 (Reuters) - Movie studio Warner Bros went ahead with Tuesday's London premiere of "Batman v. Superman: Dawn of Justice," its new superhero movie, but skipped the traditional red carpet press interviews following the attacks in Brussels.

"Our hearts go out to the victims of recent terrorist attacks, their families and the communities impacted around the world. Rather than yield to terror, we've decided to join the film's fans and move forward with the London premiere of 'Batman v. Superman' this evening," Warner Bros. said in a statement.

The movie, which stars Ben Affleck as Batman and Henry Cavill as Superman, is due to open in movie theaters around the world this weekend.

It (Other OTC: ITGL - news) is one of the biggest movie launches so far this year and is expected to bring in some $300 million at the global box office on its opening weekend, according to analyst predictions.

The London premiere took place in the city's Leicester Square (NYSE: SQ - news) entertainment hub where Affleck, Cavill and other stars turned up, posed for photos, and signed autographs for hundreds of fans.

At least 30 people were killed and some 230 injured in suicide bomb attacks on Brussels airport and a rush-hour metro train in the Belgian capital. Islamic State claimed responsibility.

Britain, along with other European states, announced extra security measures on Tuesday following the Brussels attacks. (Reporting by Jill Serjeant and Reuters television; Editing by Steve Orlofsky)
