Matte object without shadow catching problem

[Oxidizer]

Hello there

is there a way to use a diffuse material with the matte option selected but without catching a shadow?
Cutting off all objects from view & giving a clean matte in other words?

I want to matte all animated objects outside the cube-world ( car, people, elements ) from view....

Kind regards and many thanks in advance to anyone who can help me... im lost on this one`...
