Firestorm is a 2013 Hong Kong action film written and directed by Alan Yuen, produced by and starring Andy Lau.

[6] In addition, Firestorm also had its North American premier at the 57th San Francisco International Film Festival on 3 May 2014.

[7] Chief Inspector Lui Ming-chit and ex-con To Shing-bong are secondary school classmates who competitively practiced judo together.

Right after To was released from prison for robbery, he immediately re-joins Cao Nam and his gang to highjack an armoured car transporting cash.

The Regional Crime Unit later discovers the corpse of one of Cao's underlings and the burnt remains of the getaway vehicle.

Cao’s gang had shot Tong and threw his 10-year old autistic daughter off the building who eventually succumbs to her injuries.

To then meets with Lui and informs him the mastermind behind the previous armoured car heist and the murderer of Tong and Yuen-yiu is actually Cao's sworn brother, Paco, who was recently released from prison.

Lui initially considers shooting him but ultimately decides not to, but To was unexpectedly run over by an oncoming truck and dies.

After giving his testimony, Lui asks the officer whether the storm is over and shows a sign of gratefulness after given yes as an answer.

Filming locations included North Point,[8] Government House and Hong Kong Zoological and Botanical Gardens in the Central and Sheung Wan areas.

Derek Elley of Film Business Asia gave a positive review praising the acting, especially by Andy Lau and Gordon Lam, strong characters and action sequences, referring it as "one of the best Hong Kong shoot-'em-ups in recent memory, with top playing and action.

[12] On the other hand, James Marsh of Twitch Film gave the film a mixed review, praising it for having "a vibrant, kinetic aesthetic that attempts to keep its audience in a state of breathless anticipation throughout" and also criticising "the over-reliance on computer-generated effects and the almost total absence of plot or characterisation make Firestorm an incredibly loud, yet hollow experience.
