It's not Arial, it's Univers (http://www.linotype.com/1212814/univers-family.html) the stallwart font of 80s school textbooks. If only the print and the motion designers could agree on the logo! Looks like the titles could do with a tweak as they look a bit rushed at the moment too.
Question Time
I'm glad someone pointed out that they've recoloured the old titles because I thought I could see them in there! Obviously they've done a bit more than recolour them and chucked other graphical bits on top, but I was sure I could see the old titles through the mist! They're not great, and the end of the titles where the logo is in an odd gradient whilst the BBC logo isn't is a bit weird, but the set is quite nice (minus the 'Question Time' written at the side in what looks like Arial!).
