Plot Twist: James Marsden Has A 15-Year-Old Son, And They Look Exactly Alike

In a plot twist straight out of “Westworld,” James Marsden has a look-alike robotic host teen son.

See for yourself:

James Marsden brought his son Jack along to the SAG Awards on Sunday.

Given Marsden’s youthful appearance, many viewers were shocked to learn the actor was over 40, let alone the fact he has a 15-year-old son.

Jack is James’ son with Lisa Linde, his former wife of 11 years. Linde and Marsden divorced in 2011. The pair also has an 11-year-old daughter, Mary James.

Even more confusing to fans than Jack’s age was his striking resemblance to his father.

What is this magic? Allow us to advance one theory:

Just kidding! We’re sure it’s just the power of genetics, not the machinations of a team of scientists.

Well ... 99.8 percent sure.
