Jim was a veteran of the BBC visual effects department and contributed effects to an enormous number of episodes of Dr Who and Blake's 7, plus many other BBC shows. Jim co-ran SFX-GB, out of Shepperton Studios, and had recently worked on programmes such as Red Dwarf VIII, The Tenth Kingdom, and Kevin And Perry Go Large, as well pop videos for the likes of David Bowie, Tina Turner, and Red Hot Chilli Peppers.
He is survived by his wife and daughter, and a son and daughter from his previous marriage.
Jim can be seen on the far left of this picture, which is taken from the
Together Again: Seven audio tape.
There is a longer obituary by Sheelagh on The Kaldor City Site but be warned it is very slow.
