Your Lego collection is about to get a whole lot nerdier, with the announcement that a set based on geek-centric sitcom The Big Bang Theory is being released, while ones adapting the likes of Doctor Who and Back to the Future are being considered.

In total, there are six sets currently planned for sale or under review, the four most pop culture-focussed being The Big Bang Theory, the Jules Verne train from Back to the Future Part III, a multiple regeneration-spanning


Doctor Who and Companions set, and a slightly more TARDIS-focussed Doctor Who kit. The more educationally-minded Lego Bird Project offers detailed recreations of real avians, while the modular Apple storeis an unholy realisation of brand obsession.

The sets came about as a result of the Lego Ideas site, which allows fans to vote on user-created sets. Any creation gaining 10,000 votes of support within a year of its submission goes forward for official review, where Lego's board of designers, marketers and legal reps decide whether to make it a legitimate product. Of the current six, Lego Ideas' Peter Esperson confirms both The Big Bang Theory and Lego Birds are definitely receiving a physical release, although pricing, final design and release dates are yet to be confirmed.

However, getting 10,000 votes on the Ideas site isn't a guarantee of a project getting made, especially when it comes to licensed properties. Back to the Future is hopefully an easy pitch at least though, given Lego has already partnered with Universal Pictures to release a bricky DeLorean.

Esperson also says one of the Doctor Who sets is being closely considered. This could be tricky, not least because the BBC has already released construction kits based on the show through licensee Character. There may be contractual obstacles to realising the proposed Lego sets.

Esperson adds that "the next review phase is already underway, and this time it's going to be an even bigger one. Eight amazing creations qualified to be in the next review period." In among that batch, the Lego board will be evaluating Lego Batman -- Assault on Wayne Manor, the X-Men's X-Mansion, and Pixar's Wall-E. You may be waiting a while for an adorable plastic robot to call your very own though -- none of the new wave are going to be confirmed until at least January 2015.
