Will the groundbreaking animation studio, who managed such an impressive run over the four years between Ratatouille and Toy Story 3, now slink into mediocre middle age with a slew of insipid sequels? Or can they surprise us again with searing successors to imaginative fare like Up and Wall-E?&lt;/p&gt;&lt;p&gt;&lt;/p&gt;&lt;p&gt;A few clues were offered last weekend at the D23 event in Anaheim, California &ndash; a sort-of mini-Comic Con for Disney fans. The big news was the announcement of two new Disney/Pixar films.&lt;/p&gt;&lt;p&gt;&lt;/p&gt;&lt;p&gt;Untitled Pixar Movie About Dinosaurs, as it&#039;s currently known, will reportedly be released for Christmas 2013. It seems the film will imagine a world in which human beings and dinosaurs co-exist, as concept art showed a small boy sitting on the head of a brachiosaurus. Bob Peterson, the co-director of Up, is in charge for that one.&lt;/p&gt;&lt;p&gt;&lt;/p&gt;&lt;p&gt;Project number two is Untitled Pixar Movie That Lets You See Inside The Human Brain, which has Up&#039;s main man Pete Docter in the hot seat. The film-maker said it would examine &quot;how we forget, why certain songs get stuck in our heads &hellip; It&#039;s a place that we&#039;ve all been to but have never seen&quot;.&lt;/p&gt;&lt;p&gt;&lt;/p&gt;&lt;p&gt;A further synopsis reads: &quot;Pixar takes audiences on incredible journeys into extraordinary worlds: from the darkest depths of the ocean to the top of the Tepui mountains in South America; from the fictional metropolis of Monstropolis to a futuristic fantasy of outer space. The inventive new film will take you to a place that everyone knows, but no one has ever seen: the world inside the human mind.&quot; The movie will be arriving in May 2014, so there&#039;s plenty of time for Docter and his team to work out how to get inside our heads.&lt;/p&gt;&lt;p&gt;&lt;/p&gt;&lt;p&gt;Before then, Pixar has celtic fairytale Brave and Monsters Inc sequel Monsters University on its slate. Rumours of a fourth Toy Story film remain unconfirmed, but the studio announced that a new Toy Story short, Small Fry, in which Buzz Lightyear finds himself left behind in a fast-food restaurant, will debut ahead of the new Muppets movie (released in the US in November). UK filmgoers will have to wait until February, when The Muppets arrives here.&lt;/p&gt;&lt;p&gt;&lt;/p&gt;&lt;p&gt;Elsewhere, fans were treated to new footage from The Avengers &ndash; Disney-owned Marvel studios&#039; forthcoming superhero epic, which unites Iron Man, Thor, The Hulk and Captain America on the big screen for the first time. The quartet are up against Thor villain Loki (played by Tom Hiddleston). The new scenes showed Hiddleston squaring off against Samuel L Jackson&#039;s Nick Fury, and another in which the former tells Robert Downey Jr&#039;s Iron Man that he has an army ready to fight. The response? &quot;I have a Hulk!&quot;&lt;/p&gt;&lt;p&gt;&lt;/p&gt;&lt;p&gt;The Avengers is due out in the UK next May.&lt;/p&gt;&lt;div class=&quot;related&quot; style=&quot;float: left; margin-right: 10px; margin-bottom: 10px;&quot;&gt;&lt;ul&gt;&lt;li&gt;&lt;a href=&quot;http://www.guardian.co.uk/film/pixar&quot;&gt;Pixar&lt;/a&gt;&lt;/li&gt;&lt;li&gt;&lt;a href=&quot;http://www.guardian.co.uk/film/animation&quot;&gt;Animation&lt;/a&gt;&lt;/li&gt;&lt;/ul&gt;&lt;/div&gt;&lt;div class=&quot;author&quot;&gt;&lt;a href=&quot;http://www.guardian.co.uk/profile/benchild&quot;&gt;Ben Child&lt;/a&gt;&lt;/div&gt;&lt;br/&gt;&lt;div class=&quot;terms&quot;&gt;&lt;a href=&quot;http://www.guardian.co.uk&quot;&gt;guardian.co.uk&lt;/a&gt; &amp;copy; 2011 Guardian News and Media Limited or its affiliated companies.
