Fans of Walt Disney’s animated original Dumbo have already seen an elephant fly, back in 1941. What more can a modern update bring to the big top? In the hands of Tim Burton – back on enchanting form after a duo of duds – the answer is a well considered story expansion and consistently gorgeous visuals. Disney’s digital Dumbo is every bit as adorable as one could hope and twice as empathetic. With the whole film apparently occurring either at dawn or dusk, this is hardly remarkable stuff but gosh it’s nice.
