They are blazing the promo trail with the latest Avengers movie.

So the cast of Avengers: Infinity War, including Tom Holland, Pom Klementieff, Tom Hiddleston and Benedict Cumberbatch, were naturally keen to look their best at every turn - this time during the South Korea premiere of the movie.

The trio of British heartthrobs looked dashing in well-tailored ensembles as they were joined by their uber glam co-star at the event held at the COEX mall's Special Outdoor Stage in Seoul on Thursday.

Proving just why they have heartthrob status, Tom and Benedict looked extremely handsome in their sharp suits.

The Night Manager star, who plays Loki in the Marvel movie, was showing off an unkempt beard while sporting stylish glasses to compliment his three piece suit.

Benedict meanwhile, who stars as Doctor Strange in the superhero universe, went for a burgundy ensemble with a black tie.

Tom was more dressed down than his co-stars as he sported a white crew-neck T-shirt tucked into tight jeans while rocking a long-line grey coat.

Pom, who plays Mantis in the film, looked sensational in a lilac ensemble complete with a bejewelled skirt, silk shirt and suedette over-sized jacket on top.

Speaking of her turn in the film, she said: 'Acting was something that I wanted to do when I was little, but I never really tried and thought that it wasn’t possible.

'But I thought, I’d rather try and do things, because anything can happen in life. I didn’t want to have any regrets'.
