Printf isn't used like that. It is used in a similar way as scanf. You should:
printf("When %s, actorname filmed %s, filmname
he was %sage, years old. %s, actorname is currently
%age, and he is a Zodiac sIGN, %sfilmname was made %s, filmage)
The actorname is printed instead of the first %s, the filmname instead of the second %s etc.
printf("blah blah %s blah blah %s", actorname, filmname);
Another thing you don't understand probably is that you don't use the %s for everything. If you want to have a number you should use the %d, that is for integers.
And at last, I suppose you didn't compile the program. Start a little by little. One thing, compile, run. Another thing, compile, run. This way you will learn step by step what you do wrong and what not. The compiler errors will help you
printf("What is the actors birthday?"\n);
