Which actor is Shirley MacLaine's brother?

did they have same parents?

I ran into Shirley McLaine at the Newport Beach Cheesecake Factory. We gave each other a friendly smile. She knew I recognized her and we both went about our own business. I believe she appreciated being left alone.

Shirley is way better than her brother. Although the two dont acknowledge each other and haven't for years.

Player #699435, good question because they look nothing alike

He's a good actor, but, Shirley rules 😜.

I guess they each look like the mother and the other the father.😄
