It was one of those rare star-studded and high-voltage red carpet events and righfully so. Pottermania struck fans and stars alike as the last installment of the iconic series -- Harry Potter and The Deathly Hallows Part 2 -- had a world premiere in Trafalgar Square, in central London, last night.

The famous trio -- Daniel Radcliffe (Harry Potter), Emma Watson (Hermione Granger) and Rupert Grint (Ron Weasley) -- poses for pictures as they make their way for the screening.

Emma Watson, 21, outdid herself when it came to her chosen outfit for the evening. The actress looked resplendant in an Oscar de la Renta tulle dress.

The dress was as magnificent as the guest list for the premiere. Well played.

It was a remarkable night for fans too as this marks the end of an era. Thousands of fans gathered at Trafalgar Square to get a glimpse of their favourite actors and maybe an autograph or two.

Emma obliges some of the lucky ones.

Redhead Bonnie Wright arrives at Trafalgar Square. She plays Ginny Weasley, Harry's love interest. It's heartwaring to see how the central characters have evolved over the years.

Check out the earrings on Bonnie. So ladylike! 

And here comes the one who shall not be named! Yes, that's Ralph Fiennes who plays Harry's arch enemy Lord Voldemort in the series.

Helena Bonham Carter, known far and wide as quite an eccentric dresser, arrives sporting an interesting headgear for the premiere.

She plays Bellatrix, one of Voldemort's most loyal Death Eaters.
