It isn’t every day that Flash and Supergirl would cross universes for a musical “Duet,” so The CW is going all out to preview next Tuesday’s extravaganza. In addition to an extended trailer, check out dozens more photos of the big numbers, including some familiar Legends getting their dance on.

We’ve seen a few previews so far, but Flash and Supergirl’s musical meeting is finally upon us. Barry and Kara share a soulful “Duet” in the first full trailer, squaring off against Darren Criss’ Music Meister in a race to the final curtain.

We’re just one week away from Barry and Kara singing their super-hearts out when The Flash and Supergirl meet for a musical “Duet,” but why wait? Ahead of a full trailer, DC goes behind the scenes with a new all-access featurette teasing Darren Criss’ Music Meister, familiar faces and a show-stopping number.

We’ve still an episode or so before Flash and Supergirl cross universes for a musical “Duet,” but why wait for the dress rehearsal? Our first footage has arrived, featuring Melissa Benoist and Grant Gustin in their Sunday best.

Now that we’ve crossed over into March, Flash and Supergirl are warming up for the big two-night musical crossover starting on March 20. Synopses for both episodes have arrived, the first of which includes Teri Hatcher’s arrival, but Music Meister’s machinations are … somewhat disappointing.

It’ll be a cold day in hell when Batman joins the ranks of Arrow, Flash, Supergirl or Legends of Tomorrow on The CW, but LEGO has a way of bringing everyone together. See for yourself, as a new promo features the CW stars voicing their LEGO counterparts opposite Will Arnett’s LEGO Batman as part of a weeklong promotion.

Long before Flash and Supergirl confirmed their musical crosover “Duet,” fans pointed to the shared Glee past between Grant Gustin and Melissa Benoist as proof of concept. Now, their Music Meister fittingly hails from the same hallowed halls, as Darren Criss signs on to musically menace the Super-duo.

Seeing as we could all use something lighter to think about, Supergirl and The Flash are officially reporting for rehearsal of their big musical crossover. Not only has The CW set a late March debut for the showstopping two-part event, but we also know which Arrow-verse stars will flex their pipes.

Flash fans are long-used to The CW’s take on the Scarlet Speedster’s duds, which themselves have been subject to minor tweaks through Seasons 2 and 3. Grant Gustin is certainly ready for the CW series to upgrade Barry Allen, but what timey-wimey troubles might prevent The Flash from altering its title hero’s look?

The Flash got off to a less-than-speedy start in Season 3, so what better occasion to look back at the DC drama’s ups and downs? Just in time for the next run, The Flash gets the Honest Trailer treatment, and you’ll never not notice Grant Gustin’s bobbling head again.
