Robert Downey Jr. travels with his own furniture.

The 'Avengers: Age of Ultron' star, who has son Exton, three, and six-month-old daughter Avri with wife Susan Downey, reportedly shipped some of his favourite items from his home in Malibu, California to his rental house in Atlanta in a bid to feel more at home there while he is shooting 'Captain America: Civil War'.

A source close to the 50-year-old actor told Us Weekly: ''Whenever he rents a place, he has all the same furniture sent there so there's consistency from rental to rental. It comes in big semis. He does it for a sense of comfort.''

The actor, who also has 21-year-old son Indio from a previous marriage, also regularly brings his family on location with him and recently admitted his youngest children are very competitive.

He said: ''I mean it's natural for Exton to want to bite her once in a while. It can start off as a little peck and then it turns into a nibble.

''I think it's just establishing dominance but she'll be running stuff at some point.''
