ROGUE ONE: ENEMY FRIENDLIES?

Tensions rise at the Yavin IV Rebel base between General Draven and X-wing fighter squadron Blue Leader (General Antoc Merrick), in this possibly staged image from Rogue One: A Star Wars Story. though all the official book releases linked to the film in 2016 talk about the uneasy relationship between the two men, with Blue Leader considering Draven to be too ready to sacrifice the brave U-wing pilots in their battles against the Empire. It's likely that this plot element between the two characters was filmed but ultimately deleted.

Onscreen, Draven certainly came across as a pretty ruthless and stern military leader. Though in the originally filmed version of Rogue One: A Star Wars Story, he was seemingly less cutthroat as a strategist leader, and it would be his character who'd commit the Rebel ships and fighters to the attack on Scarif. In the reshoots this was changed with the introduction of the Calamarian Admiral Raddus, who'd defy the Rebels' mandate with his cruiser and support Jyn's mission to steal the Death Star plans, spurring the others fractions on to assist them.

ROGUE ONE: CONCERNING THE DEATH STAR...

On Yavin IV, Mon Mothma, her Rebel generals and tacticians, and important senators, gather to look at a hologram of the Death Star and work out their next strategy, in a deleted scene from the original version of ROGUE ONE.

There's lots to assume from this deleted scene and the alternate decision making presumably made by the Rebellion. We assume the intimidating visual of the Death Star was part of Galen Erso's message to Jyn and that she didn't lose it on Jedha as seen in the finished movie. Note that Cassian Andor, presumably speaking on Jyn's behalf and to give support, is present in this meeting when he's barely seen in the re-filmed sequence, which would also be minus the Death Star graphic or any kind of hologram. Presumably, in the original cut, the Rebellion took a more proactive decision to join forces with Jyn's plan to capture the schematics. In the reshoots, their continued doubts about Jyn, and their inability to fight alongside her, were surely added, making her final journey to Scarif more dramatic.

Alternate version, with no Cassian.

Another consideration as to why the scene was changed could be that it might have been deemed too similar to the briefing room scene with Mon Mothma and the Rebels occurring by the time of RETURN OF THE JEDI.

ROGUE ONE: MOTHER OF THE REBEL ALLIANCE!

The newly released TOPPS character/autograph card.

If Bail Organa of Alderaan was the bold father of what would eventually become known as the Rebel Alliance against the corrupt and merciless Galactic Empire, then Mon Mothma of Chandrilla must surely be its strongly beating, compassionate and vital mother heart, known for her calm, rational thinking and strong moral intellectualism ever since she was a respected leader within the troubled Republic Senate at the time of the Clone Wars, the tumultuous three years of battle and tragedy of which she now knows she and the thousands of senators she worked with for peace were being manipulated and betrayed by the man they thought they knew and trusted: Supreme Chancellor Palpatine, whose new order has wrought such hardships, terror and destructive force against the galaxy, and especially towards non-humanoid species.

A genuine baptism of fire for Mon Mothma and the Rebel Alliance in ROGUE ONE: A STAR WARS STORY.

Mon Mothma (Genevieve O'Reilly) and General Draven (Alistair Petrie) with an important new ally.

As the Empire grows more powerful, and the testing of a deadly new weapon is imminent, the small resistance cells scattered across the galaxy must finally unite and pull their resources like never before, under the leadership of Mon Mothma.

And fight... 

Mon Mothma, as seen in publicity materials for EPISODE III.

With her scenes for EPISODE III sadly removed from the original theatrical release (though available on DVD), Genevieve O'Reilly's presence in the first ROGUE ONE trailer as Mon Mothma, with a visage and clothing that matched Caroline Blakiston's character/look from RETURN OF THE JEDI, was a welcome and truly satisfying sight, fusing the Prequel and Classic Trilogy saga's together even more strongly.
