Revenge of the Fallen film
Sentinel Prime led an expedition where it took him fourteen galactic convergences to get an echo of something.
Whether or not he is one of the original Primes or in the later Dynasty of Primes is uncertain. He does however seem to be one of the direct ancestors of Optimus Prime.
Sentinel Prime was mentioned in a rambling lecture of Sam Witwicky's while under an AllSpark fragment-induced trance. Revenge of the Fallen
IDW live-action film comics

Sentinel Prime was a direct descendant of the first Cybertronian, Primus, and was believed to be the last of the Primes. He told tales to his much younger Cybertronian brethren of how the Dynasty of Primes had called upon a legendary artifact, the star-powered AllSpark, to give life to their world. But the AllSpark had been lost to history, and their world had tumbled through the cosmos without a star to orbit for eons.
Sentinel Prime had plans to rectify this, and he gathered followers who believed in his path to a new age of life on Cybertron. With the help of Optimus, Megatron, and their legions, they searched the planet for the legendary artifact and a way to power it. However, there were the Thetacons, a tribe of separatist Transformers who disbelieved in Sentinel Prime's vision, and warred against him and his followers. This conflict ended when, with the help of Wheeljack, a sun to orbit was brought to Cybertron, and the AllSpark discovered and energized.
Though Sentinel Prime had finally returned the forgotten concept of "freedom" back to Cybertron, he felt he no longer had a part in its path to the future. He was old and tired, and spoke in confidence to Optimus, wishing for the young Autobot to become the new Prime. Though Optimus was too humble to accept, Megatron overheard their conversation and became jealous of his "brother." Foundation issue 1 Sentinel formulated another plan for Cybertron's future: it would be governed by Optimus's Science Division and Megatron's Defense Force. By having Optimus investigate the remains of the Primes's civilization, it would encourage him to believe in his lineage. Foundation issue 2

- MechTech Leader Class Sentinel Prime converts from a Rosenbauer Panther Airport fire truck to robot and back! He comes with a shield and the Primax blade, a double-bladed sword thingy. When a button on his chest is pushed, his chin moves and he says "I am Sentinel Prime!" Two more phrases, "Good to see you alive, Optimus." and "What has happened to the AllSpark?" are heard when the button hidden in the 5mm port by his right shoulder is depressed and the chest pushed. The Canadian release only says "Sentinel Prime" because of language laws. Additionally, siren lights and sounds can be activated by pressing a gray button back and to the left of Sentinel Prime's head. The hidden 5mm port button also produces transformation and machinery noises when pressed.

Notes
- In an early draft of Transformers, time stops as Sam Witwicky falls down the building Megatron smashed, and Sentinel appears to him via the AllSpark. Sentinel would've clarified the history of the war and the relationship between Optimus and Megatron (when the writers intended them to be siblings) and given him a clue to defeating Megatron with the Cube.[1]
- In an interview with MTV, Michael Bay is quoted as saying "Sentinel Prime is great. He's great...I can't tell you anything else, other than he's great."[2]
- His a traitor to the Autobots.
