McGregor will feature in LG's advertising campaigns for the Australian and New Zealand markets. His to the point strapline for the advertisements, "LG is f***ing great, all the others are crap" drew howls of laughter from the assembled media, but is unlikely to form part of the marketing campaign.
Also coming up from LG are smaller and lower priced 55 and 65 inch versions of its Ultra High Definition TV, which has four times the resolution of standard HDTVs. Last year, LG was first to market with an UHDTV, but at 84 inches in size, the screen is just too big for most households.
LG is also betting that people will start to appreciate Smart or internet connected TVs more, despite a survey the company had commissioned which showed that many customers didn't even know their sets had that particular feature.
As part of the Smart TV move, LG launched a new Magic Remote with gesture controls for pointing, drawing and scrolling, which are easier to use than traditional button remotes for things like moving around on web pages.
Cloud storage is also available for LG's Smart TVs, with 5GB of space on which to keep streaming content, and the Time Machine II programme recording feature for the built in Freeview tuners, that lets you hook up external USB drives to the sets.
