Who would have thought that John Cena - old Fruity Pebbles himself - would somehow blossom into a hilarious comedy actor specialising in cameos and support roles? After the success of Trainwreck and the lesser impact of Sisters, the hulking WWE star stole the mostly abysmal Daddy's Home from Mark Wahlberg and Will Ferrell by turning up right at the end as the alpha male Dad whose child Wahlberg becomes step dad to. He's on screen for a matter of seconds, but it's a brilliant touch that actually calls back to the imaginary friction between the two established by his cameo in Trainwreck. Just wait until WWE has them facing off in an in-ring feud.
