Call another controller ActionResult from Different Controller

If I have a controller in CatalogControllers called bespoke. It accepts the parameter of categoryid.

I have another controller called bespokecontroller, which has a view called bespoke. The view contains:

@Html.Action("bespoke", new { CategoryID = 8})    

and the controller has:

public ActionResult Bespoke(int CategoryId)
        {
            return null;
        }

What I want to do, is from the bespoke action result, call the bespoke action result from the catalogcontroller?

I've tried RedirectToAction("CatalogController", "Bespoke",CategoryId) but that throws an error. Anyone got any advice?
