You might have luck using the GIMP Animation Package. This is a third-party package that adds functionality which is useful for working on animations. It allows to apply a filter on all layers.

Just use the 'Repeat' action, at the top of the Plugins menu, for each layer. I have a keyboard shortcut assigned to it, so I can just press PgUp, R, PgUp, R....

I think I have only had to do something like this once. But yes GAP does have a nice add-on that puts in an menu entry for "filter all layers".

There are other things that GAP comes in handy for. You can use it to make image pipe brushes that would otherwise be a lot of work to do in regular Gimp.

I don't like to have Gimp without it, and I imagine there are a lot of Gimpers who think likewise.

Thanks Sven -- this seems unreasonable, though, to have to install a plug-in for animation
in order to use a tool on all layers. I could not figure any way, so I flattened and
saved under a new name and ran the curve/bend on the new file.

I wonder if other Gimp users find this to be a limitation.

Hi Helen,

This works for some filters, but not for the curve/bend. Because each layer needs to bend
as a unit consolidated with the whole, but the repeat function bends each layer in a way
that doesn't blend with the whole.
Now I'm thinking, I wonder whether your suggestion might have worked, it I had made each
layer the same size and situated each layer with that outcome in mind.

If you do 'Layers->Layer to image size' for each layer before applying the curve, does that give a result more like what you want?
