Things people forget about Charlie Weasley:

He was Quidditch caption and seeker

He had the skills to play Quidditch professionally, but choose to go to Romania and study dragons

He was in the same year as Nymphadora Tonks

He was a perfect at Hogwarts

He was the best man at Bill and Fleur's wedding

He was assigned by Dumbledore to recruit foreign wizards for the Order of the Pheonix

The only time we see him in the movies is in the Daily Prophet picture of the Weasley family in Prisoner of  Azkaban
