In February this year, Channel 4 (in the UK) showed a drama / documentary, titled "Krakatoa".

Being written by script-writers, with reputable vulcanologists and geologists allowed only a few out-of-context quotes, and the drama laid on with a trowel, thereby diminishing rather than emphasising the scale of the disaster, it missed the point a little. However, the computer-generated effects were good, and the way the diaries and oral traditions of witnesses to the eruption were well portrayed.

It had presumably been made some time ago, but was shown in the wake of the Boxing Day tsunami disaster, with comparisons of the earlier and recent disasters.
