1. How I Met Your Muggle
If there's one thing that the first half of Doctor Who Season Seven proved, it's that Mark Williams is a true British acting gem who should never be dismissed. In that case, then, there's a prime opportunity for Warner Bros to have Williams reprise his role as none other than Arthur Weasley, dealing with an all manner of fascinating and comedic Muggle inquiries as was hinted at in the earlier novels and films. From discovering the true purpose of a rubber duck to working out just how normal humans manage without wands, Mr Weasley's comedy hi-jinks could have endless potential as another humorous TV spin-off. Those are my ideas for just where the Harry Potter franchise could head in the future on the small screen, but the possibilities are endless. Which iconic characters from the series would you like to see return for further televisual adventures?
