Imelda Staunton and Jim Carter – 37 years

The 64-year-old stage and screen actress attended the Royal Academy of Dramatic Art and has been a figure to reckon with in the world of theatre. She has been a part of many plays and musicals such as The Wizard of Oz, Uncle Vanya, and others. Staunton became more popular with her portrayal of Dolores Umbridge in two films of the iconic Harry Potter franchise.

Staunton and the Downton Abbey actor, Jim Carter, have been in a marital relationship since 1983. All has been well between the two, and it looks like nothing is potent enough to separate them from each other. With sufficient funds under their belts, the couple has never had to contemplate asking for a bankruptcy attorney to intervene. Staunton, Carter, and their daughter, Bessie, starred together in Cranford, the BBC series.
