Actor Jake Gyllenhaal showed off the impressive jump roping skills he learned while training to portray a boxer in his new film Southpaw during an interview with U.S. talk show host Ellen DeGeneres on Monday (27Apr15). The Brokeback Mountain star answered pop culture trivia questions while expertly hopping, and raised $10,000 (£6,250) for his favourite charity, New Eyes, which provides glasses for people who can't afford them.
