The actress told SFX that she watched the films of Katharine Hepburn and Spencer Tracy to get a handle on the dynamic between her character and the Doctor (Matt Smith).
"When I started on Doctor Who, Matt said to me, 'Watch Katharine Hepburn and Spencer Tracy films!' - we were talking about our dynamic and trying to figure it out, realising we were a double act," she explained.
"It's trying to find each other's rhythm... so watching things like Spencer Tracy films really fed into that."
Coleman claimed that the relationship between 'impossible girl' Clara and Smith's Time Lord is "like a dance".
"Matt always said it's about physically finding our rhythm," she continued. "In a way the whole thing is like a dance, and the moment we started dancing together and finding that rhythm is when it worked."
Doctor Who returns to BBC One and BBC America on Saturday, March 30 with 'The Bells of St John', written by Steven Moffat.
