You’re aware of the system - Tom Cruise is an “A” list celeb, while someone who was immediately kncoked out of Britain’s Got Talent in 2011 is a “Z” list celeb. This thread will determine where all* celebrities rank at the current time. They can be alive or dead, UK or not.
For the purposes of this we will rank from A to E, plus Z as it is more amusingly cruel than F. As a twist, you can also rank them nationally and internationally - for example, Declan Donnelly might be borderline A-list in the UK, but E-list internationally.
