Crazy Kurt Russell is the best Kurt Russell.
We don't know what world James Corden and Hollywood legend Kurt Russell would be friends but we're glad that in this imagined one, Russell's at least fulfilling the role of borderline psychotic frenemy who seems intent on making sure Corden knows who the alpha dog is at all times.
If you're looking for more crazy Kurt Russell, can we suggest Quentin Tarantino's 'Death Proof' which features possibly the most deranged Kurt Russell you could hope for.
