Now Hawaii Five-O 7:00PM M*A*S*H

Here's how the 'M*A*S*H' cast changed from their first to last episodes

Characters can look rather different after a decade.

M*A*S*H is a rare example of a show that can survive major cast changes. At the end of the third season, fan favorites Trapper John and Henry Blake were written off the show, allowing for the arrival of newcomers like B.J. Hunnicutt and Sherman Potter.

Adding new characters is always a risky move, but it paid off big time for M*A*S*H. The series continued to rate highly and became one of the longest-running sitcoms of all time.

A lot can happen over the course of 11 years. The cast can change, but the cast members themselves can change too. Here's a look at what the actors looked like for their first and last episodes of the series.
