Question: Indicate the name of the actors of the films rated as 'Parents Strongly Precautioned' with the highest replacement cost.
Evidence: name refers to first_name, last_name; Parents Strongly Precautioned' refers to rating = 'PG-13'; 
highest replacement cost refers to MAX(replacement_cost)

SQL:
SELECT T1.first_name, T1.last_name FROM actor AS T1 INNER JOIN film_actor AS T2 ON T1.actor_id = T2.actor_id INNER JOIN film AS T3 ON T2.film_id = T3.film_id WHERE T3.rating = 'PG-13' ORDER BY T3.replacement_cost DESC LIMIT 1
