While I generally thought that the casting in Harry Potter was excellent (Michael Gambon aside), one thing the casting directors were consistently off with was the age of the characters, in particular Harry's parents and their contemporaries at Hogwarts. This is a trend that continued with Sirius Black. Oldman was 45 or 46 when he played Black in Prisoner of Azkaban; Sirius was 33 during the events of that film. I'd also pictured Sirius very differently from how he looked in the film; he was shorter and better groomed that I'd generally pictured him.

It's hard to recast any of the key roles played by the younger actors like Daniel Radcliffe, Emma Watson and Rupert Grint, so all of my choices for actors who should've appeared in the Harry Potter franchise correlate to the many supporting roles for adults.

Jeremy Irons: He played quite a vicious uncle in The Lion King as the devious Scar, but maybe he could've been the warm, consoling godfather to Harry Potter as Sirius Black. Then again, his previous villainous turns (Die Hard with a Vengeance, The Time Machine) prove that he would be quite a good Severus Snape or maybe even Lord Voldemort.
