Scarlett Johansson left the promotional duties to Cobie Smulders this weekend.

The brunette actress joined co-stars Chris Hemsworth, Robert Downey Jr., Mark Ruffalo and Chris Hemsworth on the red carpet on Saturday night for the Tribeca Film Festival premiere for ‘The Avengers’.

Opting for another bold colour, Cobie looked stunning wearing a Reem Acra Spring 2012 gown.

Her orange-crepe v-neck gown with embellished cap sleeves was styled with complementary gold accessories including a Judith Leiber clutch, a Ippolita gladiator cuff and statement earrings plus a H.Stern ring.

A sophisticated updo and nude lippie completed her look.
