Does He At Least Call Before He Drops In?

I guess there was a time when a production  just  wasn't a Production until Cary Grant came a-calling on the set:

Cary Grant visits Joan Crawford, Wm. Castle and John Ireland on the "I Saw What You Did" set.

Grant visits Frank Capra and James Stewart on the "Mr. Smith" set.

Grant visits Deborah Kerr on the "Young Bess" set

Grant visits Cab Calloway and Eartha Kitt on the "St. Louis Blues" set.

Grant visits Paul Newman and Joanne Woodward on the "Winning" set.

....And apparently the same held true for 
locker rooms!

Grant visits Yogi Berra.
