Over the Thanksgiving holiday weekend, Deadline Hollywood Daily is debuting a series of "Speechless" videos, in which an impressive roster SAG actors (Holly Hunter! Harvey Keitel! David Schwimmer?) , take to these revenue-deficient internets to silently express their solidarity with their WGA peers. Especially mesmerizing is yesterday's clip of the always-outspoken Sean Penn, who, forced into a rare silence by the ongoing strike, seems to calmly mouth a threat to unseen AMPTP negotiators, warning them that he'll be waiting outside Monday's revived contract talks ready to beat some sense into anyone who refuses to bargain in good faith.
