Those David Tennant casting rumors continue. But what's the truth?

David Tennant is—once again—being rumored for a role in Peter Jackson's The Hobbit. This time it seems that the actor is set to play the Elvenking Thranduil, aka Legolas' dad. But is there any truth in this?

Though the name of the former 10th Doctor Who has already been bandied about a few months ago, the rumors were fueled again yesterday when Movieweb posted a story about Tennant possibly playing the father of our favorite pointy-eared elf, Legolas' (Orlando Bloom, also rumored to be making a cameo appearance in the film).

The site is basing its story on the Hobbit: Part 1 cast list from IMDb, a good source for all things data on movies, TV series, actors and such, but perhaps not the best source for casting news. (To be fair, IMDb does say that the casting is a RUMOR, but if you look closely the "retired" Leonard Nimoy is also being rumored for the voice of the dragon Smaug.)

Unlike some of the returning cast from The Lord of the Rings, Thranduil IS an important supporting character that appears in The Hobbit, and he also happens to be one of the only (major-ish) parts that have yet to be filled.

Now the thing is, Tennant—who will next be seen as Peter Vincent in the upcoming Fright Night remake—has just signed on to star in William Shakespeare's Much Ado About Nothing with his former Doctor Who companion, actress Catherine Tate. The play opens in London in May and will run until Sept. 3.

If the rumors are true, and Tennant will indeed play Thranduil, the film's production can probably work around the actor's schedule in order to accommodate him. After all, according to Bleeding Cool, that's what they're doing with the film's main star, actor Martin Freeman, who is said to be filming The Hobbit in New Zealand from January until May before returning to London to film the second series of Sherlock right until December.

So is there any truth to that story? It's possible, since the rumors about Martin Freeman and James Nesbitt (who was cast as Bofur) did pan out to be true. Moreover, Tennant's name has been out there for a good while now, first for Bilbo Baggins and then for an undisclosed role.

Do we want it to be true? Yep, we have have to say that we do. Tennant DOES have the Elvish look about him, and he's a great and well-loved actor.

But what do YOU think? Do you believe there's any truth to this rumor? And do you WANT it to be true?
