But the actress who brings Claire’s character to life is played by popular actress Caitriona Balfe. He has done an incredible job bringing the character to life, showing his strength and intelligence.

The actress keeps her both a great chemistry with actor Jamie Fraser, Sam Heughan, which makes the love story of the series is even more charming.

But the reality is that the actress who was going to play Claire, according to the Mental Floss diary, was going to be a popular actress from Grey’s Anatomy, Katherine Heigl.
