If you haven't already done so, check out the Bible Society's Bible Sunday resources. You have to register (free) to access them, but there are some great things there.
There is a really excellent drama called Bible Brasserie as well as film clips, prayers and hymn/song suggestions, and some childrens and youth resources. I'm not sure, but I think one of the films is deliberately being ironic (I'm not arty enough to know) - it is about audio Bibles, with everything it says in writing - a good film but excludes anyone in this country who cannot read or see (I think that's the down side of the clever ironic twist I perceive).
Well worth a gander, even if you don't intend keeping Bible Sunday this year. Several intertwined themes, so hopefully you'll find something worth using.
(Here in Dibley it's a great excuse to sing the likes of 'God has given us a book full of stories' - which is better theology than much more recent stuff on the Bible)
