Hill is the go-to guy for bromances

Jonah Hill will never be able to shoulder a movie on his own. That's the awful truth.

In Hollywood, where looks outweigh talent, the rotund 32-year-old US actor is just not leading man material.

But he has made his mark as the go-to guy for bromances, the fella whose role is to make his male co-stars look good.

He broke out playing Michael Cera's stoner mate in Superbad (2007).

He was Brad Pitt's unlikely right-hand man in Moneyball (2011), which gave Hill his first best supporting actor Oscar nomination.

He paired up with Channing Tatum for the buddy cop comedy 21 Jump Street (2012) and its 2014 sequel.

Hill then earned another best supporting actor Oscar nomination as Leonardo DiCaprio's partner in crime in The Wolf Of Wall Street (2013).

And now, he's set to prop up Miles Teller in War Dogs, opening here on Sept 1.

It's the crazy-but-true story of two young Americans David Packouz (Teller) and Efraim Diveroli (Hill) who, made millions by selling ammunition to the US military during the Iraq War.

Directed by The Hangover's Todd Phillips, who also wrote the screenplay, the film is based on a Rolling Stone article in 2011, The Stoner Arms Dealers, about the duo's rise from small-time weapons traders to international arms dealers.

Hill's brazen, morally corrupt and manipulative Diveroli is so annoying and unscrupulous, he makes Teller's Packouz appear like the saint.

It doesn't help that Hill has ballooned even more for the role, while Teller still sports the physique from his Fantastic Four days.

Hill again plays the sidekick, helping his down-and-out comrade and introducing him to the lucrative business of war.

This role is tailor-made for Hill, one that's already winning plaudits from US critics.

His performance is so impressive, a group of South African arms dealers reportedly went up to Hill in a restaurant to high-five him after seeing the film's trailer.

War Dogs probably won't lead to a third best supporting actor Oscar nomination but it certainly cements Hill's status as Hollywood's best supporting friend.
