UPDATE, 2:06 PM: Looks like a former Time Lord and a Hogwart wizard will be National Television Awards - Winners Roomsitting down for supper with President Barack Obama tomorrow night. The Guardian will be bringing exDoctor Who star David Tennant and Alan Rickman, who played Severus Snape in the Harry Potter pics among his many roles, to the White House Correspondents’ Dinner in Washington D.C. on Saturday. New "A Little Chaos" - UK Premiere - Red Carpet ArrivalsGuardian Editor-in-chief Katharine Viner as well as various staff members of the UK-based paper will join the two. Turner Prize-winning artist Chris Ofili and actress Georgia Moffett, who is married to the 10th Doctor and Gracepoint actor, will also be guests of The Guardian at the self styled Nerd Prom. In fact, the Guardian table will be a bit of Potter reunion as Tennant was in the fourth pic in the hugely successful franchise. The actor played Barty Crouch, Jr. in 2005’s Harry Potter and the Goblet of Fire. Tennant played Doctor Who from 2005 to 2010 and appeared in the 50th Anniversary special in 2013. We hear that Bradley Cooper may be in the house tomorrow too as a guest of TIME and that Homeland‘s Rupert Friend will be there as well.

PREVIOUS, APRIL 22 PM: The President of the United States is the marquee name at the annual nerd prom but Barack Obama has some serious star power competition in the room at this weekend’s White House Correspondents’ Dinner. With Saturday Night Live‘s Cecily Strong as the lead jokester, the 101st dinner of the D.C. journalist organization will see cast members of ratings blockbusters The Walking DeadModern Family, Empire and Game Of Thrones in attendance on April 25 along with a two-time Oscar winner and Scandal’s Olivia Pope.

First In The Nation Republican Leadership Summit Held In New HampshireFox News Channel is certain to cause a stir in the Washington Hilton ballroom by inviting perpetual almost Presidential candidate Donald Trump this year. Like actor Tim Daly, House Of Cards‘ Michael Kelly and some members of the Modern Family cast, this is a return visit for The Celebrity Apprentice boss. A guest of the Washington Post at the 2011 WHCD, Trump was ripped relentlessly by Obama and host Seth Meyers. No word if there is going to be a repeat performance but this year there’s also going to be a fictional female Secretary of State, a real life female ex-Secretary of State and a fictional female Commander-In-Chief at the tables – but no Hillary Clinton.

We’ll update with more names as we get them but here is the Hollywood contingent for the 2015 WHCD so far, plus the odd cabinet secretary and high ranking member of Congress or two.
