'Iron Man' hitmaker Eric Kwok is looking forward to his Coliseum shows

Looking at his thick eyebrows and toned skin, it's easy to understand why Canto-pop hitmaker Eric Kwok Wai-leung has been dubbed Hong Kong's own Iron Man. The Robert Downey Jnr lookalike even served as poster boy for a local restaurant chain in which he was depicted as Iron Man in a series of TV commercials.

"I wasn't sure if I wanted to do it when the chain approached me. I thought I may look stupid if it wasn't executed well," Kwok says with a slightly embarrassed grin. "But it turned out to be fun." It's not just that Kwok bears a physical resemblance to Downey and the American comic hero he plays. Like Tony Stark, Kwok himself is something of a man-child, or a "kidult".

In his collaborations with long-time friend Eason Chan Yik-shun and with his own pop duo, Swing, Kwok has always searched for fun — as well as a groove — in the local Canto-pop scene.

His latest single, a plug for his upcoming retrospective concerts at the Hong Kong Coliseum, has the straightforward title Iron Man. The electronic rock/nu metal tune depicts the ups and downs of being an "iron man".

The music video, of course, features Kwok wearing Tony Stark's famous suits and sunglasses. "The best part was casting female models for the club scene," Kwok jokes. "I haven't had the chance to look at so many girls at the same time in a long while."

While he usually lives a low-profile and quiet life, Kwok made headlines on local entertainment pages in 2011 when he proposed — and married on the spot — his long-time girlfriend, singer Grace Ip Pui-man, at a Swing concert, turning the gig into one big wedding party.
