The boxing film Southpaw, backed by a $30 million production investment from Chinese property developer Dalian Wanda Group, took in $20 million during its opening weekend at United States and international box offices.

The film starring Jake Gyllenhaal is the first investment in a US movie by Wanda, which owns the second-largest US movie theater chain, AMC Entertainment Holdings Inc, according to The Wall Street Journal.

In addition to Wanda's investment, the Weinstein Co spent $35 million marketing the film, according to the newspaper, and the two companies will split any profit.
