How I Met Your Mother has cast Barney's brother, and he will be played by... Wayne Brady. Adoption? Half sibling? "The less we say about it, the funnier it will be," exec producer Carter Bays tells Variety. "We like that 'What the hell?' factor." Thus far, Brady is only booked for a single, Nov. 27 appearance, but the role may become recurring (as has Bryan Cranston's gig as Ted's boss).... Per the Hollywood Reporter, Frances Fisher ( Titanic) and Ivan Sergei ( Charmed) have joined the cast of the USA Network pilot To Love and Die in L.A., respectively playing the mother and love interest of Shiri Appleby's daughter-of-an-assassin.
