SEASON FINALE: Paul Rudd has hosted the season finale of SNL three times – and tonight’s show will make his fourth. Why is he tapped so often for this particular slot? For one thing, he’s usually featured in a major summer movie – as he is, this year, playing Ant-Man in Avengers: Endgame. But it’s also because Rudd can be counted on to hold his own in any sketch, and even carry it – which, at the end of a long season, when the regular Saturday Night Live repertory players are sucking wind and trying to make it to summer vacation, is a big, big plus.
