Hollywood star Leonardo DiCaprio researched his The Wolf of Wall Street co-star Margot Robbie by watching old episodes of Neighbours.
DiCaprio had never heard of the TV soap which launched Robbie's career before working with the Australian star.
Robbie has now revealed that DiCaprio delved into her past by viewing instalments of the long-running drama on video-sharing website YouTube.
The actress admits she was mortified when she found out the actor was watching her soap appearances online.
"He actually YouTubed Neighbours because he was wondering what everyone kept referring to so he YouTubed it. And I was so angry that he had, I was like, 'Don't ever do that again it's really embarrassing'... I was always doing something so embarrassing or was dressed weird," Robbie told New Zealand radio station The Edge.
