The father-son bond in The Rifleman remains one of the greatest in TV history, even 60 years later.

However, this storyline fizzled out when Milly left the show in season four, with a vague explanation that she needed to head back east.

This left producers in search of a new female lead, introducing the character Lou Mallory. The challenge was to find an actress who not only fit the role but also had undeniable chemistry with Chuck Connors.

To ensure a successful match, Chuck was actively involved in the casting process. However, this turned out to be more challenging than anticipated. Chuck interviewed over a dozen women who seemed perfect for the part but just didn’t quite click.

”A few months ago, I was handed what I thought was a dream assignment. At least it started out on a dreamlike note but almost snowballed into becoming a nightmare,” the actor shared.

After carefully considering over 60 women, the choice ultimately fell to the stunning red-haired beauty Patricia Blair, who hailed from Texas.

Recognize this baseball hall-of-famer?

As previously mentioned, Lucas McCain was an incredibly skilled baseball player. However, he could never match the prowess of former Dodgers star Duke Snider, who made a guest appearance on the show. (Chuck Connors hit only two home runs during his Major League Baseball career).

The celebrated baseball player, nicknamed “the Duke of Flatbush,” portrayed the character Wallace in the episode titled The Retired Gun. Another former baseball star who made an appearance on the show was Don Drysdale.

Johnny Crawford’s brother popped up

The Rifleman was heavily centered around family themes, and it was the first network television series to portray a single parent raising a child.

In addition to Jeff Connors, another relative of the show’s stars made an appearance: none other than Bobby Crawford, brother of Johnny.
