Low-key arrival! A chipper Christian Bale displays his long dishevelled hair as he touches down in Los Angeles

He has spent the past few weeks filming his latest Hollywood movie, The Big Short.

And on Saturday, Christian Bale appeared to be in great and relaxed spirits as he touched down in Los Angeles following a long-haul flight.

Unable to hide his smile, the 41-year-old actor displayed quite the low maintenance look, with his long brown hair flowing free in dishevelled waves.

He dressed down in a pair of loose-fit cargo pants and an oversized navy coloured jumper, which was coupled with white-soled sneakers.

Christian, who is married to 44-year-old Sibi Blazic, was seen pushing an empty pushchair along the terminals while making his way through flashing cameras.

The star and his wife are parents to their nine-year-old daughter Emmeline and an eight-month-old son, whose name is yet to be confirmed.

The award-winning actor continues to maintain his long locks a year after wrapping Exodus: Gods And Kings.

However, for his role in forthcoming film The Big Short, the Welsh star donned a wig and emerged with a bare face while shooting scenes last month.

He has been spending a lot of time in Louisiana to work on the drama, which has been adapted from Michael Lewis' bestseller The Big Short: Inside the Doomsday Machine. 

Christian portrays Michael Burry, the founder of the Scion Capital, who earned millions during the U.S. housing and credit meltdown that led to the 2007-2008 global financial crisis. 

He stars alongside Brad Pitt, who is also producing the Adam McKay-directed film as well as playing Cornwall Capital's Ben Hockett. 

Meanwhile, Ryan Gosling has taken on the role of Deutsche Bank trader Greg Lippman and Steve Carell is enlisted to star as FrontPoint Partners money manager Steve Eisman.
