If you already implemented a base controller just override its OnActionExecuting() method:

public class YourBaseController : Controller
{
    protected override void OnActionExecuting(ActionExecutingContext filterContext)
    {
        base.OnActionExecuting(filterContext);

        if(somethingIsWrong)
        {
            filterContext.Result = new RedirectToRouteResult(
                new System.Web.Routing.RouteValueDictionary { ... });
        }
    }
}
