Acer has launched an online spot featuring the DJ Tiësto. The three-minute film, created by Mother, broke last week on YouTube and promotes the brand’s Aspire P3 Ultrabook. The protagonist in the ad is Tiësto’s assistant, Vernon, who uses his Acer computer to organise his boss’ diary and also to explore his own love of music. Vernon and his Ultrabook end up saving the day by taking the reins at a gig when Tiësto gets trapped inside a giant bubble. The work, which also features the model Poppy Delevigne, was directed by Traktor. Post-production was handled by The Moving Picture Company, while audio post-production was by 750mph.
